5.3 Registering the Oracle VM Manager

The Oracle VM Manager provides the user interface that allows you to create and manage zones, virtual server pools, virtual servers, and guest virtual machines. Before you use the Oracle VM Manager to manage virtualization targets in Enterprise Manager, you must register an existing installation of the Oracle VM Manager.

Note:

  • The Oracle VM Manager that you register with Enterprise Manager must be at least version 3.0.2 or higher.

  • The Oracle VM Manager must be associated with only one Enterprise Manager installation.

  • As a best practice, it is recommended that the Management Agent and the Oracle VM Manager are present on the same physical machine.

  • If you are registering Oracle VM Manager 3.3, you must ensure that the Enterprise Manager for Oracle Virtualization (Oracle Virtualization) plugin 12.1.0.7 or a later version has been deployed on the Oracle Management Service and the Management Agent.

To register the Oracle VM Manager, you must first add it as an Enterprise Manager target. To do so, follow these steps:

  1. From the Enterprise menu, select Cloud, then select Oracle VM Infrastructure Home.

    Figure 5-2 Infrastructure Cloud Home

    Infrastructure Cloud Home Page
  2. From the Infrastructure Cloud menu, select Register OVM Manager. The Add Oracle VM Manager page appears.

  3. Figure 5-3 Add Oracle VM Manager

    Add Oracle VM Manager

    You can register an existing installation of Oracle VM Manager by following these steps:

    Prerequisites

    • If you are registering OVM Manager 3.1.1 or later, before you update the Oracle VM Manager URL, you must have configured tcps as described in Note 1490283.1.

    • You must have imported the Oracle VM Manager certificate to the Agent keystore by following these steps:

      • Export the OVM Manager certificate <JAVA_HOME>/bin/keytool -keystore <OVM_MANAGER_HOME>/ovmmCoreTcps.ks -exportcert -alias ovmm -file <file_loc_for_certificate>

      • Import the OVM Manager certificate <AGENT_INSTANCE_HOME>/bin/emctl secure add_trust_cert_to_jks -trust_certs_loc <file_loc_for_certificate> -alias <alias_name>

        If the certificate is being imported for multiple Oracle VM Managers, you can specify multiple alias names.

    • If you are registering Oracle VM Manager 3.3, in addition to importing the Oracle VM Manager certificate, you must export the Oracle VM Manager WebLogic certificate and import the certificate to the Agent Keystore. See Section 5.3.3, "Importing the Oracle VM Manager WebLogic Certificate" for details.

    1. Enter the target name for the Oracle VM Manager instance to be registered.

    2. Select the Management Agent to monitor and manage the Oracle VM Manager instance to be registered. It is recommended that the Management Agent (with Enterprise Manager for Oracle Virtualization plug-in (listed as Oracle Virtualization in Self Update) is present on the same machine where the Oracle VM Manager instance is running.

    3. Enter the Oracle VM Manager URL. Refer to Note 1490283.1 for details on configuring Oracle VM Manager for tcps access.

      The URL must be in one of the following formats:

      - tcp://localhost:<port>. Example: tcp://localhost:54321 (If the Oracle VM Manager version is 3.1.1 or greater, you can specify only the tcps URL.)

      - tcps://<hostname:<port>. Example: tcps://server.domain:54322

    4. Enter the Oracle VM Manager's Console URL. This is the URL to enable the VNC Console for the Guest VMs. For example, https://ovmmgr.example.com:7002/ovm/console

      The URL must be in the following format:

      https://<hostname>:<port>

      Note:

      If you are registering Oracle VM Manager 3.3, this URL is used to connect to the Oracle VM Manager.
    5. By default, data from Oracle VM Manager is automatically synchronized with Enterprise Manager at fixed intervals of time. If you do not wish to enable this option, you must disable the Automatic Synchronization checkbox and manually synchronize the data. For more details on the automatic and manual synchronization options, see Section 5.4, "Synchronizing the Oracle VM Manager Targets" for details.

    6. Enter the administrator user name and password to connect to the Oracle VM Manager URL provided in Step C. If you want to use separate credentials for managing Oracle VM Manager, check the Use Administration Credentials check box. If these credentials are not specified, the monitoring credentials are used by default.

    7. Click Submit to register the Oracle VM Manager. You can now use the Oracle VM Manager to monitor and manage the virtualization targets in Enterprise Manager.

5.3.1 Port Requirements for Oracle VM Manager Setup

The ports required for the Web browser connection to Oracle VM Manager are 7002 and 15901. TCP 7002 is used by the Oracle VM Servers to connect to Oracle VM Manager. Oracle VM Manager, in turn, connects to the Oracle VM Servers through port 8899 for Oracle VM Agent communication, and port 6900 and up for secure VNC tunneling to virtual machines (one port per VM). Ports 7900 and up are used to allow Oracle VM Manager to open secure serial console tunnels to virtual machines (one port per VM) on the Oracle VM Servers. The Oracle VM Command Line Interface connects to Oracle VM Manager on port 10000. TCP ports 54321 and 54322 must be enabled for remote API access to the Oracle VM Manager core. Follow the guidelines of in the diagram below:

Figure 5-4 Oracle VM Manager Firewall Configuration

Oracle VM Manager Firewall Configuration

5.3.2 Updating the Oracle VM Manager URL

If you had Oracle VM Manager 3.0.x registered with Enterprise Manager previously and had upgraded it to higher versions 3.1.x or 3.2.1, you must update the Oracle VM Manager URL.

If you are upgrading to version 3.3, you must also import the WebLogic certificate. See Section 5.3.3, "Importing the Oracle VM Manager WebLogic Certificate" for details.

Prerequisites

  • Before you update the Oracle VM Manager URL, you must have configured tcps as described in Note 1490283.1.

  • You must have imported the Oracle VM Manager certificate to the Agent keystore by following these steps:

    • Export the OVM Manager certificate <JAVA_HOME>/bin/keytool -keystore <OVM_MANAGER_HOME>/ovmmCoreTcps.ks -exportcert -alias ovmm -file <file_loc_for_certificate>

    • Import the OVM Manager certificate <AGENT_INSTANCE_HOME>/bin/emctl secure add_trust_cert_to_jks -trust_certs_loc <file_loc_for_certificate> -alias <alias_name>

To update the Oracle VM Manager URL, follow these steps:

  1. Right click on the OVM Manager target that is to be upgraded and select Edit.

  2. Enter a tcps based (tcps://hostname:port) URL in the Oracle VM Manager field.

    Note:

    It is recommended that you use the tcps based URL. But if the Management Agent is running on the same host on which Oracle VM Manager has been installed, you can use the tcp based URL (tcp://localhost:54321).

5.3.3 Importing the Oracle VM Manager WebLogic Certificate

Oracle VM Manager 3.3 contains an internal Certificate Authority (CA) that is used to perform certificate-based authentication and to sign the SSL certificate that is used for the web-based user interface. Certificates are generated automatically when Oracle VM Manager is installed.

To export the Oracle VM Manager WebLogic certificate, enter the following command:

#/u01/app/oracle/ovm-manager-3/ovm_upgrade/bin/ovmkeytool.sh exportca > <file_loc_for_certificate>

To import the Oracle VM Manager Weblogic certificate to the Agent Keystore, enter the following command:

<AGENT_INSTANCE_HOME>/bin/emctl secure add_trust_cert_to_jks -trust_certs_loc <file_loc_for_certificate> -alias <alias_name>

Note:

The first line in the <file_loc_for_certificate> must be deleted before the OVM Manager certificate is imported.

5.3.4 Discovering and Promoting the Oracle VM Manager (Optional)

Automatic discovery is a process that detects hosts, Oracle VM Managers, and other targets so that they can be monitored and managed by Enterprise Manager. If you know the Oracle VM Manager instances in your environment, see Section 5.3, "Registering the Oracle VM Manager" for details on registering them with Enterprise Manager. Discovery and promotion of Oracle VM Manager should be attempted if you want to scan your networks to discover unknown Oracle VM Manager instances.

To discover an Oracle VM Manager, follow these steps:

  1. Log in to Enterprise Manager as a user with the Super Administrator role.

  2. From the Setup menu, select Add Target, then select Configure Auto Discovery.

    Figure 5-5 Configure Auto Discovery

    Configure Auto Discovery
  3. In the Network Scan-based Auto Discovery table, click Configure Network Scan Discovery in the Host and Oracle VM Manager row. The Network Discovery page appears. Use this page to search, browse, and create OVM Manager discovery specifications.

    Figure 5-6 Network Scan Discovery

    Network Scan Discovery
  4. Click Create. The Network Scan Discovery: Create page appears.

    Figure 5-7 Network Scan Discovery: Create

  5. Enter the Name and Description for the Discovery Specification. Click Add in the Network Scans region to select the Agent that is to be used perform the IP scan. For each Agent, specify the IP ranges for the scan. The following formats are supported: host name, IP address, and IP range. Use space to separate values.

  6. Use the Job Details tab on the Host Discovery Specification Create page to schedule the discovery IP scan, allowing you to start it immediately or at a later specified time. Use the Credentials section to enter preferred credentials for the host. You can choose from Preferred Credentials, Named Credentials, or New Credentials. The discovery IP Scan is run as root. It is required that you set privileged host credentials or named credentials that use Sudo.

  7. You can use the Host Discovery page to check the status of discovery and view newly discovered OVM Managers.

  8. After the target has been discovered, from the Setup menu, select Add Target, then select Auto Discovery Results. Enterprise Manager displays the Auto Discovery Results page where you can review discovered unmanaged targets and promote targets to be managed by Enterprise Manager for monitoring.

  9. On the Network-scanned Targets tab, the target discovery results are displayed in the table at the bottom. Select the OVM Manager target and click Promote. The OVM Manager Registration page is displayed. See Section 5.3, "Registering the Oracle VM Manager" for details.

5.3.6 Upgrading the Oracle VM Manager

To upgrade from earlier versions of Enterprise Manager and Oracle VM Manager to Oracle VM Manager 3.3, follow these steps:

  1. Upgrade Oracle Management Service to 12.1.0.4 and deploy the Oracle Virtualization 12.1.0.7 plugin.

  2. Upgrade Management Agent to 12.1.0.4 and the deploy the Oracle Virtualization 12.1.0.7 plugin.

  3. Blackout the old Oracle VM Manager target.

  4. Upgrade the Oracle VM Manager to 3.3.1. For more information, see the Oracle VM Installation and Upgrade Guide for Release 3.3.

  5. Upgrade the Oracle VM Server to 3.3.1. For more information, see the Oracle VM Installation and Upgrade Guide for Release 3.3.

  6. Import the WebLogic certificate. See Section 5.3.3, "Importing the Oracle VM Manager WebLogic Certificate" for details.

  7. Change the blackout status of the Oracle VM Manager target.

  8. Add or modify the target property if required. For example, Webservice URL using Edit Oracle VM Manager page.

5.4 Synchronizing the Oracle VM Manager Targets

Enterprise Manager can monitor the OVM Manager and the various virtualization targets registered with the OVM Manager. The targets registered with the OVM Manager must also be monitored targets in Enterprise Manager. If some targets have been created directly in OVM Manager, you can synchronize them in two ways:

  • Automatic Synchronization

  • Manual Synchronization

5.4.1 Automatic Synchronization

You can enable this option when Oracle VM Manager is registered or when you Edit Oracle VM Manager. If the Automatic Synchronization option is enabled, all changes made in Oracle VM Manager are automatically reflected in Enterprise Manager at fixed intervals. The default interval is 1 minute. To change the default interval, follow these steps:

  1. From the Enterprise menu, select Cloud, then select Oracle VM Infrastructure Home.

  2. Select an Oracle VM Manager target from the right panel to navigate to the Oracle VM Manager Home page.

  3. From the Target menu, select Monitoring, then select Metrics and Collection Settings.

  4. Click Other Collected Items and then click the Collection Schedule link for the OVM Manager Events Data metric.

  5. Modify the frequency as required, click Continue, then click OK.

    Note:

    If you do not enable automatic synchronization at this time, you can enable it later by following these steps:
    • Navigate to the OVM Manager homepage.

    • From the Target menu, select Target Setup, then select Edit OVM Manager.

    • Select the Automatic Synchronization check box and click Submit.

5.4.2 Manual Synchronization

When the Oracle VM Manager is registered, if the Automatic Synchronization option is enabled, for the targets created in Oracle VM Manager, corresponding targets are created in Enterprise Manager. If, this option is not enabled, you can manually synchronize the targets by following these steps:

  1. From the Enterprise menu, select Cloud, then select Oracle VM Infrastructure Home.

  2. Right click on an OVM Manager target from the left panel and select Synchronize.

  3. A confirmation message appears. Click Submit to submit a job to perform synchronization. The targets in Enterprise Manager and OVM Manager are synchronized.

    • Targets that are not present in OVM Manager will be removed.

    • For targets present only in OVM Manager, corresponding targets are created in Enterprise Manager.

    • Configuration collections are refreshed for all other targets.

5.5 Discovering a Virtual Server

A virtual server is a generic term used to describe a physical box which has virtualization software (hypervisor) running on it. A new virtual server can be provisioned by installing the OVM Hypervisor on a bare metal box. Before you add a virtual server to a server pool, it must be discovered.

To discover an Oracle VM Server, follow these steps:

  1. From the Enterprise menu, select Cloud, then select Oracle VM Infrastructure Home.

  2. Right click on an OVM Manager target from the left panel and select Discover Virtual Server.

    Figure 5-9 Discover Virtual Servers

    Discover Virtual Servers
  3. Specify the host name or the IP address of the virtual server. You can enter multiple host names or IP addresses on separate lines.

  4. Enter the user name and password of the Oracle VM Agent running on the virtual server to be discovered.

  5. Click Submit to discover the virtual server.

The newly discovered Oracle VM Server contains some basic information about itself, and about any immediate connectivity to a network storage, but it is considered to be in an unconfigured state. After the storage and networking has been configured, the Oracle VM virtual servers are ready to be used as the infrastructure for cloud.

5.6 Rediscovering a Virtual Server

To rediscover a virtual server, follow these steps:

  1. From the Enterprise menu, select Cloud, then select Oracle VM Infrastructure Home.

  2. Right click on a Virtual Server target in the left panel and select Rediscover Virtual Server.

  3. A confirmation message appears. Click OK to rediscover the virtual server and discover any new NICs and LUNs that have been added.

5.7 Setting Up Networks

This section discusses creation and use of Oracle VM Networks. You can define a name or an alias for each logical network. When you have created your networks, you connect the physical network ports on Oracle VM Servers to the logical networks. Before you define the logical networks in Enterprise Manager, you have to review your physical network configuration that you intend to use, such as VLAN and subnet usage. Setting up an Oracle VM network involves:

5.7.1 Generating MAC Addresses

Virtual network interfaces (VNICs) are used to carry network traffic to virtual machines. You can generate MAC addresses that can be assigned to VNICs in a virtual machine. Specify a range of MAC addresses that need to be generated.

VLAN Group has been replaced with VLAN Interface and during Vlan interface configuration, it asjs VLAN Segment ID's and then Select Ports of Servers where the Interfaces to be created"

Note:

MAC addresses must be unique across all Oracle VM Managers in the data center.

To create MAC Addresses, follow these steps:

  1. From the Enterprise menu, select Cloud, then select VM Infrastructure Home.

  2. Right click on an OVM Manager target from the left panel and select Manage Network.

  3. Figure 5-11 Virtual Network Interface Card Manager

    Networks
  4. Click the Virtual Network Interface Card Manager tab.

  5. Click Generate. In the Generate MAC Addresses pop-up window, you are prompted to specify an initial MAC address in 3 sets of 3 characters. This is a two-digit number for the Initial MAC Address. Click OK to return to the previous page. You can now use these VNICs while creating virtual machines.

5.7.2 Configuring a VLAN Group for Oracle VM Manager 3.2 or Earlier Versions

Note:

Configuring a VLAN Group is an optional feature. If VLANs exist in your physical network, you must follow the steps in this section to use them in the cloud.

VLAN (Virtual Area Network) is a mechanism to virtualize network interfaces across subnets and physical location so that they appear to be on a single confined LAN. This concept is used to isolate (and group) the network traffic across these distributed interface, which enables secure network traffic within such nodes.

You can create multiple virtual LAN (VLANs) on the same NIC port. Each VLAN is an independent logical network operating with other VLANs over the same physical connection. Configuring VLANs involves creating one or more VLAN Groups, each of which contain multiple VLANs segments.

Each VLAN is assigned a distinct VLAN identification. The VLAN ID is used by an attached VLAN switch to segregate traffic among the different VLANs operating on the same link. Once a VLAN is configured, it functions exactly like a separate physical connection. VLANs need to be configured in the physical switches before you use them. To create a VLAN group, follow these steps:

  1. From the Enterprise menu, select Cloud, then select Oracle VM Infrastructure Home.

  2. Right click on an OVM Manager target from the left panel and select Manage Network.

  3. Click the VLAN Groups tab and click Create.

  4. Enter a name and description for the VLAN Group.

  5. Enter one or more VLAN Segments. This is the VLAN ID that is enabled on the switch ports connecting the virtual server to the switch. The valid range is from 1 to 4094.

  6. Click Add to select the ports to be added to the network. Select one or more virtual servers to be added to the network. If you add more than two ports of a virtual server, the first four ports will be bonded. Network bonding refers to the combination of network interfaces on one host for redundancy or increased throughput.

    If your network supports jumbo frames, you must set the Maximum Transfer Unit size in the MTU field. Setting the MTU field, sets the maximum transmission rate, so that larger packets can be sent and received. You can set the MTU to a maximum of 1500 for Ethernet, 9000 for 1GbE, and 64,000 for 10GbE.

    Note:

    The ports that you have selected must have the VLAN Segment IDs enabled.
  7. Click OK to create the VLAN Group.

5.7.3 Creating a VLAN Interface for Oracle VM Manager 3.3

Note:

Configuring a VLAN Interface is an optional feature. If VLANs exist in your physical network, you must follow the steps in this section to use them in the cloud.

VLAN (Virtual Area Network) is a mechanism to virtualize network interfaces across subnets and physical location so that they appear to be on a single confined LAN. This concept is used to isolate (and group) the network traffic across these distributed interface, which enables secure network traffic within such nodes. VLANs are divided into segments that are usually tagged with an ID.

To manage network traffic tagged for different VLAN IDs, a separate VLAN or virtual interface can be created for each VLAN ID. When creating different logical networks in Oracle VM Manager, these VLAN interfaces can be attached to different networks to specify the type of traffic that belongs to a particular VLAN ID.

If your network is configured to support VLANs, you should define interfaces for your different VLAN IDs on each of your servers, so that you are able to define Oracle VM networks that take advantage of VLAN separation.

You can create multiple virtual LAN (VLANs) on the same NIC port. Each VLAN is an independent logical network operating with other VLANs over the same physical connection. Configuring VLANs involves creating one or more VLAN Interfaces, each of which contain multiple VLANs IDs.

Each VLAN is assigned a distinct VLAN identification. The VLAN ID is used by an attached VLAN switch to segregate traffic among the different VLANs operating on the same link. Once a VLAN is configured, it functions exactly like a separate physical connection. VLANs need to be configured in the physical switches before you use them. To create a VLAN Interface, follow these steps:

  1. From the Enterprise menu, select Cloud, then select Oracle VM Infrastructure Home.

  2. Right click on an OVM Manager target from the left panel and select Manage Network.

  3. Click the VLAN Interfaces tab and click Create.

    Figure 5-12 Create VLAN Interface

    Surrounding text describes Figure 5-12 .
  4. Enter one or more VLAN Segments separated by commas.

    VLANs are divided into segments that are usually tagged with an ID. The ID is enabled on the switch ports connecting the virtual server to the switch. The valid range is from 2 to 4094.

  5. Click Add to select the ports to be added to the network. In the Create VLAN Interfaces: Add Ports page, click the Search icon next to the Select Virtual Server(s) field. Select one or more virtual servers to be added to the network and click Select. The list of ports with the MTU size, MAC Address, and status is displayed. Select the ports to be added and click Continue. If you select more than one port of a virtual server, they will be bonded. Network bonding refers to the combination of network interfaces on one host for redundancy or increased throughput.

  6. The selected ports are displayed. You can modify the following for each port:

    • MTU: If your network supports jumbo frames, you must set the Maximum Transfer Unit size in the MTU field. Setting the MTU field, sets the maximum transmission rate, so that larger packets can be sent and received. You can set the MTU to a maximum of 1500 for Ethernet, 9000 for 1GbE, and 64,000 for 10GbE.

    • Address Type: The network address assignment type can be Static, Dynamic, or None.

    • IP Address: The IP address for the port.

    • Netmask: The netmask for the port.

    • Bonding Mode: Network bonding refers to the combination of network interfaces on one host for redundancy and/or increased throughput. This can be:

      • Active-Backup: There is one NIC active while another NIC is asleep. If the active NIC goes down, another NIC becomes active.

      • Load Balancing: The network traffic is equally balanced over the NICs of the machine and failover is also supported to provide redundancy.

      • Link Aggregation: Aggregated NICs act as one NIC which results in a higher throughput, but also provides failover in the case that a NIC fails.

    Note:

    The ports that you have selected must have the VLAN Segment IDs enabled.
  7. The VLAN Segments with the ports, MTU, Address Type, IP Address, and NetMask are listed in the VLAN Interfaces region. These parameters can be modified if necessary.

    Click the Manage icon to add or delete VLAN Segments and click OK and return to the Create VLAN Interfaces page. Click OK to create the VLAN Interfaces and return to the Network page.

5.7.3.1 Viewing the VLAN Interfaces

To view the VLAN Interfaces that have been added, click the VLAN Interfaces tab on the Network page. The VLAN Interfaces are listed with the following details:

  • Name: The name of the VLAN Interface that is created.

  • Port: The network port on which the VLAN Interface has been assigned.

  • Segment: The VLAN ID assigned to the VLAN Interface.

  • Server: The server where the VLAN Interface is located.

  • Network: The network to which the VLAN Interface is attached.

  • MTU: The MTU value for the VLAN Interface.

  • Address Type: The network address assignment type. This can be Static, Dynamic, or None.

  • IP Address: The IP address allocated to the VLAN Interface.

  • Netmask: The netmask applied to the VLAN Interface.

5.7.3.2 Editing a VLAN Interface

To edit a VLAN Interface, follow these steps:

  1. Select the VLAN Interface you wish to edit from the list of VLAN Interfaces and click Edit.

  2. In the Edit VLAN Interface page, you can edit the MTU setting and the Address Type. If you select Static type, you can specify the IP Address and the Netmask.

  3. Click OK to save the changes and return to the previous page.

5.7.3.3 Deleting a VLAN Interface

To delete a VLAN Interface, follow these steps:

  1. Select the VLAN Interface you wish to delete from the list of VLAN Interfaces and click Delete.

  2. The Delete Confirmation dialog box is displayed. Click OK to delete the VLAN Interface.

5.7.4 Creating Networks

A network is a grouping of Oracle VM virtual server physical NIC ports. This section describes the procedure to create a logical network.

Prerequisites

  • If you choose to associate a network profile with the network, then the network profile must be created before the network is created. A network profile stores the network interface configuration (IP address, subnet mask, host name, DNS servers) that is allocated to network interfaces of newly provisioned virtual machines.

Follow these steps to create a logical network:

  1. From the Enterprise menu, select Cloud, then select Oracle VM Infrastructure Home.

  2. Right click on an OVM Manager target from the left panel and select Manage Network.

  3. Click the Create option in the Networks tab. You are prompted to configure the ports of the VLAN groups. Click Create VLAN Groups to configure VLAN Groups.

    For Oracle VM Manager 3.3, click Create VLAN Interfaces to configure the VLAN interfaces. See Section 5.7.3, "Creating a VLAN Interface for Oracle VM Manager 3.3" for details.

    If you want to create the networks without configuring the VLAN groups or interfaces, click Continue Network Creation. In the Create Network: General page, enter the name and description of the network.

    Figure 5-13 Create Network: General

    Create Network: General Page
  4. Specify if you are creating an inter-server or intra-server network. An inter-server network is routable through standard switches. An intra-server network is available within a single server without a route to an external physical network.

  5. Specify the network role by checking one or more check boxes in the Network Roles section.

    Note:

    To deploy a Guest VM, you must have at least one logical network with the Virtual Machine role.
    • Server Management: Manages the physical virtual servers in a server pool, for example, to update the Oracle VM Agent on the different virtual servers.

    • Live Migrate: Carries live migrate traffic. You can migrate virtual machines from one virtual server to another in a server pool, without changing the status of the virtual machine.

    • Cluster Heartbeat: Carries cluster heartbeat traffic.

    • Virtual Machine: Used for the network traffic between the different virtual machines in a server pool. The virtual machine role can either be an Inter-Server (routable through standard switches), or an Intra-Server (without a route to an external physical network). The Virtual Machine role must be unique on the network, which means that this network cannot have other network roles. It is however possible, and very likely, to have multiple networks with the Virtual Machine role in one Oracle VM Manager.

    • Storage: Used for all storage transport in a server pool. It is used by the virtual servers to connect to ethernet-based storage repositories.

  6. Click Next. In the Configure Ports and VLAN Interfaces page, click Add and select a VLAN Interface from the list.

    Figure 5-14 Create Network: Configure Ports and VLAN Interfaces (OVM Manager 3.2)

    Create Network Configuration
  7. After adding the VLAN Segment, click Add the VLAN Interfaces and the ports. Select the ports to be added to network. If you select more than two ports, they will be bonded or aggregated into a single interface. By default, the Bonding Mode is Active Passive but you can change it by selecting one of the following:

    • Active Passive: There is one active NIC. If this one goes down, another NIC becomes active.

    • Link Aggregation: All NICs act as one NIC which results in a higher throughput.

    • Load Balanced: The network traffic is equally balanced over the NICs of the machine.

    If your network supports jumbo frames, you must set the Maximum Transfer Unit size in the MTU field. Setting the MTU field, sets the maximum transmission rate, so that larger packets can be sent and received. You can set the MTU to a maximum of 1500 for Ethernet, 9000 for 1GbE, and 64,000 for 10GbE.

    Note: If you are using Oracle VM Manager 3.3, you will see the following page:

    Figure 5-15 Create Network: Configure Ports and VLAN Interfaces (OVM Manager 3.3)

    Create Network:OVM 3.3
  8. Click Next. The Network Profile and QoS page appears.

    Note:

    Defining the Network Profile and QoS is optional. A network profile stores the network interface configuration (IP address, subnet mask, host name, DNS servers) to be allocated to network interfaces of newly provisioned virtual machines.

    Figure 5-16 Create Network: Network Profile and QoS

    Create Network: Network Profile and QOS

    Specify the following:

  9. Review the details entered so far and click Finish to create the network.

5.8 Creating a Network Profile

A network profile is used to automate assignment of IP addresses to guest virtual machines. A network profile is a list of IP address along with host names. It defines a set of IP addresses, their associated host-names, and common networking attributes for them.

Figure 5-17 Network Profile

Network Profile

To create a network profile, follow these steps:

  1. From the Setup menu, select Provisioning and Patching, then select Network Profile.

  2. Click Create on the Network Profile page.

  3. Enter the following details in the Create Network Profile pop-up window:

    • Name: Unique name that identifies the network profile name.

    • Domain Name: Domain for which the profile is being defined. The domain name must not begin with a dot ('.'). For example, you must specify the domain name as us.oracle.com and not with a dot ('.) in the front like .us.oracle.com.

    • Netmask: Network mask for the subnet IP. For example: 255.255.240.0

    • Gateway: Gateway for the IP address list.

    • DNS Servers: Name resolution servers.

  4. You can add a list of IP addresses or specify a range. If you select:

    • List: Specify IP addresses with host name and MAC address (optional).

    • Range: Specify a Hostname Pattern. The Start Value is appended to the host names generated. The First IP Address and the Last IP Address defines the range. For example: If the pattern is say hostprod and Start Value is 1, First IP Address is 10.1.1.1 and Last IP Address is 10.1.1.3, the host names will be hostprod1, hostprod2 and hostprod3.

  5. Click OK to save the network profile.

5.9 Registering Storage Servers

You can create external storage elements like storage servers, file systems, and LUNs. An external storage element is created on dedicated storage hardware such as a server configured for NAS offering NFS shares. The server on which the storage element is present must be accessible by the Oracle VM Servers through a fibre channel or ethernet network. You can configure a virtual server pool with multiple such external storage devices.

  7. Click Apply. A job is submitted to apply the update. The downloaded plug-in is applied and appears on the Oracle VM Templates and Oracle Virtual Assemblies Updates page.

5.14 Creating a Virtual Server Pool

This section guides you through the ways of designing a server pool to meet your requirements.

Before creating a server pool, you need to consider how many physical servers will be contained in the server pool, and what functions each physical server will perform. The more virtual machines you will run in the server pool, the more resources these virtual machines will consume, therefore the more physical servers are needed to provide sufficient resources for the server pool.A server pool is scalable. If you find a server pool does not have sufficient resources, such as CPU and memory, to run the virtual machines and the applications inside, you can expand the server pool by adding more Oracle virtual servers.

A virtual server pool contains one or more virtual servers and guest virtual machines. A virtual server can belong to one and only one virtual server pool at a time. Guest virtual machines and resources are also associated with the server pools.

Prerequisites

  • A non-clustered virtual server pool can contain a maximum of 64 Oracle VM servers and a clustered virtual server pool can contain a maximum of 32 Oracle VM servers.

  • Virtual servers that can be deployed as the Master Server, the Utility Server, and/or the Guest Virtual Machine. At least one virtual server is required in a server pool.

  • All virtual servers in a server pool should have CPUs in the same CPU family. If they are not in the same CPU family, some operations such as live migration may fail. Though the CPUs should be in the same CPU family, they may have differing configurations, such as different number of cores. Other hardware components on the host computer may also differ, such as the amount of RAM, the number and size of disk drives, and so on.

    Note:

    Although the host computers may have differing configurations, Oracle recommends that all virtual servers in a server pool are identical.
  • A dedicated file system (either a NAS export, or a LUN) to use as the server pool file system is available.

  • IP addresses for the virtual servers must be available. The IP address to be used as the Master Server's virtual IP address must be an unused and available IP address.

  • To create a virtual server pool, you must be logged in as an Administrator with Add Any Target privilege.

  • To delete a virtual server pool, you must have Full privilege on the server pool and appropriate privileges on the virtual servers and guest virtual machines belonging to the virtual server pool.

To create a virtual server pool:

  1. From the Enterprise menu, select Cloud, then select Oracle VM Infrastructure Home.

  2. Right click on an OVM Manager target in the left panel and select Create Virtual Server Pool.

    • Description: A description of the server pool.

    • Keymap: Specify the keyboard type for the guest virtual machines created in this server pool.

    • VM Start Policy: Select the policy to be used to start the virtual machines. You can choose:

      • Start on Best Server: The best server in the server pool is used to start the virtual machine.

      • Start on Current Server: The virtual machine will be started on the same server on which it was created.

    • Secure VM Migrate: Specify whether encrypted migration of virtual machines is to be enabled. If this checkbox is selected, virtual machines are migrated using SSL to protect data during the migration process.

    • Activate Cluster: Select this check box to enable high availability on the server pool.

    • Cluster Timeout: If the Activate Cluster is enabled, you can set the cluster timeout period in seconds. The disk heartbeat and network heartbeat are derived from the cluster timeout value.

    • Type of Pool File System: Select the pool file system to use for the server pool. The pool file system is used to hold the server pool, cluster data, and is also used for the cluster heartbeat.

      The type can either be Network File System or Physical Disk. If you are using a file server for the server pool, select Network File System. If you are using a physical disk on a storage array for the server pool, select the type as Physical Disk.

    • Location: Click the Search icon to search for and select the pool file system. This must be accessible by all virtual servers in the server pool.

    • Virtual IP: An IP address used to locate the Master Server in the server pool. If the Master Server changes to another Oracle VM Server, this IP address is then assigned to the new host.

  4. Click Add in the Virtual Servers section. Select one or more virtual servers from the Search window and click OK.

    Note:

    Before you add a virtual server to the server pool, it must have been discovered. See Section 5.5, "Discovering a Virtual Server" for details.
