9.8.3.1 Creating and Storing Virtualization Components in the Software Library

This section describes the procedure to create the virtualization components in the Software Library. It includes the following:

• Creating an Assembly Component

• Creating a Template Component

• Creating an ISO Component

• Creating a Virtual Disk

9.8.3.1.1 Creating an Assembly Component

An assembly is a collection of virtual machine instances. When an assembly is deployed, a group of virtual machines or an assembly instance is created.

Prerequisites

• The Assembly Binary, a file with a .ova extension must be present on the Management Agent or on an external http/ftp/nfs location.

Follow this process to create a new assembly component:

1. From the Enterprise menu, select Provisioning and Patching, then select Software Library.

2. Select a folder on the Software Library page. From the Actions menu, select Create Entity, then select Virtualization. You can also right click on a folder and select the virtualization option from the context menu.

3. From the Create Entity: Virtualization pop-up window, choose Assembly from the Select Subtype drop down list.

4. In the Create Assembly: Describe page, enter the following details:

   • Name and description of the assembly.

   • In the Attachments section, click Add to attach any files relevant to the entity. Ensure that the file size is less than 2 MB.

   • In the Notes section, include information related to the entity like changes being made to the entity or modification history that you want to track and click Add.

5. Click Next to continue. In the Create Assembly: Upload Files page, select one or more files to be associated with the assembly. You can either:

   • Upload Files: You can upload files from a storage location in the Software Library. For Software Library to become usable, at least one upload file location must be configured. Select the Upload Files option. In the Specify Destination section, click the Browse button in the Upload Location field. Two storage options are supported:

     • OMS Shared File System: An OMS Shared File System location is required to be shared (or mounted) across all the Oracle Management Server (OMS) hosts. This option is ideal for UNIX systems.

       For single OMS environments, you can configure the Software Library either on the host where the OMS is running or in a shared location, so that it is accessible to all the OMS hosts. For multiple OMS environments, Oracle recommends that you configure the Software Library in a shared location so that the storage is accessible through NFS mount points to all Oracle Management Servers in the environment

     • OMS Agent File System: An OMS Agent File System location is a location that is accessible to one of the OMS host's Agent. This option is ideal for OMS installed on Windows hosts. By selecting this option for uploading files, you can avoid sharing a location between all participating OMS hosts.

     Credentials must be set before using an OMS Shared File System or OMS Agent File System. For an OMS Shared File System, normal host credential must be set before configuring a storage location. However, for OMS Agent File System location configuration, a credential (preferred or named) has to be specified.

   • Refer Files: Select this option if you want to use an external file location where the software library files are staged. Referenced File Locations support three storage options:

     • HTTP: An HTTP storage location represents a base URL which acts as the source of files that can be referenced. For example, the base URL http://my.files.com/scripts could be configured as an HTTP location for sourcing files such as http://my.files.com/scripts/perl/installMyDB.pl or http://my.files.com/scripts/linux/stopMyDB.sh.

     • Agent: A storage location is similar to the OMS Agent File System option, but can be any host monitored by an Management Agent. The Management Agent can be configured to serve the files located on that host. For example, the directory /u01/binaries on the Enterprise Manager Host my.em.file.server could be configured as an Agent location for sourcing files such as /u01/binaries/rpms/myCustomDB.rpm or /u01/binaries/templates/myTemplate.tar.gz

     • NFS: An NFS storage location represents an exported file system directory on a server. The server need not be an Enterprise Manager host target. For example, the directory /exported/scripts is exported on server my.file.server could be configured as an NFS location for sourcing files such as /exported/scripts/generic/installMyDB.pl or /exported/scripts/linux/stopMyDB.sh once mounted on a target host file system.

     These locations require a named credential to be associated which will be used to access the files from the base location on the host through the Management Agent.

   • Specify Source: You can add additional file storage locations.

     • To add a HTTP location that can be accessed through a HTTP URL, select HTTP from the Storage Type list and click Add. In the Add HTTP Location dialog box, enter a unique name and a HTTP location for the storage that you want to reference, and click OK. A new entry for the storage location is created, with details like Name, Location, and Status.

     • To add a Management Agent location that has read-only privileges set on it, select Agent from the Storage Type list and click Add.

6. Click Next. In the Assembly Details page, you will see a set of predefined deployment profiles. You will also see the structure of the assembly and all the appliances in the assembly. Click Next.

7. On the Review page, click Save to save the assembly component. Click Upload to upload the assembly component to the Software Library.

9.8.3.1.2 Creating a Template Component

Follow these steps to create a template component:

1. From the Enterprise menu, select Provisioning and Patching, then select Software Library.

2. Select a folder on the Software Library page. From the Actions menu, select Create Entity, then select Virtualization. You can also right click on a folder and select the virtualization option from the context menu.

3. Select the Subtype as Template.

4. In the Create Template: Describe page, enter the name and description of the template.

5. Select the Operating System Name, Type, and Virtualization Type. The Virtualization Type can be Para Virtualized, Hardware Virtualized or both. Select Para Virtualized if you want use machines that are not enabled for virtualization. Select Hardware Virtualized if you want to use machines that are enabled for virtualization.

   • Para Virtualized: A virtual machine with a kernel that is recompiled to be made aware of the virtual environment. Runs at near native speed, with memory, disk and network access optimized for maximum performance.

   • Hardware Virtualized: A virtual machine with an unmodified guest operating system. It is not recompiled for the virtual environment. There may be substantial performance penalties running as a hardware virtualized guest. Enables Microsoft Windows™ operating system to be run, as well as legacy operating systems. Hardware virtualization is only available on Intel VT or AMD SVM CPUs.

6. Click Next to continue. In the Create Template: Upload Files page, select one or more files to be associated with the assembly. You can:

   • Upload Files: You can upload files from a storage location in the Software Library. For the Software Library to become usable, at least one upload file location must be configured.

9.8.4 Provisioning Guest Virtual Machines Using Oracle Virtual Assemblies (OVA)

An assembly is a packaging of a multi-tier application stack, which when deployed results in the creation of a set of related virtual machines representing every tier of the application stack. For example, a Siebel assembly can contain the Siebel mid-tier and a database. It can be deployed such that it creates 2 virtual machines for a 2-node Siebel mid-tier and 1 virtual machine running the database.

The deployment of the assembly is based on the policies/constraints defined in the assembly definition. The initial placement of virtual machines will be based on the storage, network and computational resources. Once an assembly is deployed, additional instances can be added (scale up) or removed (scale down) based on application demand.When an assembly is deployed, an assembly instance is created. An assembly instance is a collection of dependent virtual machines, which is created after an assembly is deployed. The composition of the assembly instance is dynamic in nature, as any subsequent scale-up or scale-down operations will change the membership. An assembly instance contains one or more tiers, each tier further comprising of virtual machines and or tiers.

Follow this process to deploy an assembly and create the virtual machines.

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

2. Right click on a Zone, VM Server Pool, or VM Server target and select Deploy Assembly.

   Figure 9-8 Assembly Deployment: Instance Details

   
   

3. On the Assembly Deployment: Instance Details page, specify the following:

   • Target: Select the server pool on which the guest virtual machines are to be deployed.

   • Source: You can select either of the following options:

     • Deployment Plan: If you select the Use Deployment Plan check box, you can select a deployment plan (if available) with predefined configurations. The deployment plan will be used when the assembly is deployed. (image is selected automatically when the deployment plan is selected)

     • Image: The assembly component to be used for this deployment. This can either be a component present in the Software Library, or at an external location. If it is stored in an external location, specify the NFS or HTTP location where the component is stored. For example, http://myvm_server/assembly or file://myvm_server/assembly.

   • Details:

     • Request Name: This is the name of the assembly deployment request.

     • Assembly Instance Name: The name to be assigned to the assembly instance.

     • Allow Partial Deployment: Select this option to enable partial deployment. By default, when a deployment plan fails, all virtual machines that have been created are automatically deleted. But if partial deployment is enabled, virtual machines are not deleted even if the deployment has failed.

   • Assembly Content: You can disable an assembly tier or a node from being deployed. By default, all nodes and tiers in the selected component are automatically deployed. To disable a node or tier from being deployed, unselect the Deploy checkbox in the table.

     Note:

     • A tier or a node can be disabled for deployment if the minimum number of instances for the node or tier is set to 0 in the ovf metadata file.

     • If you choose to use a deployment plan where a tier or a node has been enabled for deployment, that node or tier cannot be disabled.

4. Click Next. In the Deploy Assembly: Network and Agent page, specify the physical public and private networks to be used for the assembly instance. A public network is used for external traffic. In a private network, the guest virtual machines can communicate only within a predefined network set up by the Cloud Administrator.

   Assembly network refers to the logical network defined in the OVF metadata file and the network defined here is the actual physical network to which it is to be mapped. If you do not choose to associate the network explicitly, the mappings are automatically assigned.

   Figure 9-9 Assembly Deployment: Network and Agent

   
   

5. Click on the Browse icon in the Network field. Specify if the network should be allocated by the system or selected manually.

6. If you want to install the Management Agent on an assembly tier (collection of Guest VMs) or selected guest virtual machines, check the Enable EM Agent Push Configuration check box. You can then select the tiers and / or the guest virtual machines on which the Management Agent is to be installed using the Agent Push approach in the Assembly Node Selection for the EM Agent Push Selection table.

   • Node Name: The name of the assembly tier on which the Management Agent is to be deployed.

   • Installation Type: The type of installation which can be Push Agent Installation, No Agent Installation, and RPM Installation.

   • Enable Agent Push: This checkbox is enabled only if the Enable EM Agent Push Configuration checkbox has been selected. Select this checkbox to select the tiers on which the Management Agent is to be installed by way of the Agent Push approach.

     In a selected tier, you can also choose the guest virtual machines on which the Management Agent is to be installed.

   Note:

   • If you select Push Agent Installation, you can specify the guest virtual machines that need to be enabled or disabled in the Miscellaneous tab.

   • For tiers that have the Management Agent as a product (as part of the binary package), the Enable Agent Push checkbox is disabled and only RPM Installation is available. In this case, you can specify the Management Agent details in the Product Configuration tab of the selected tier.

7. After you have specified the options to configure the Management Agent, enter the following details:

   • Installation Base Directory: This is the parent directory on the remote host where the Oracle home of the Management Agent is created.

   • Platform: The operating system on which the Management Agent is to be installed.

   • User: The name of the Oracle Install user is displayed here.

   • Port: The port used by the Management Agent for communication.

   • Password: This field is mandatory for PS5 assemblies if the Enable Agent Push Configuration checkbox has been selected.

   • Privilege Delegation Settings: Run as root.

   • SSH Service Timeout: The timeout settings for SSH.

   • Additional Parameters: Specify additional parameters to be used during the installation of the Management Agent. This field is pre-populated with the entry -ignoreDirPrereq -enablePty to ignore the prerequisite checks during installation.

8. Click Next to go to the Deploy Assembly: Deployment Configuration page.

   Figure 9-10 Assembly Deployment: Deployment Configuration

   
   

   The following details are displayed:

   • Component: The assembly component that is being deployed.

    The following parameters can be configured:

    • Guest VM Configuration:

      • Enable High Availability: If you want to enable high availability for this guest virtual machine, select this check box. If this option is enabled, the virtual server is shut down or restarted, the guest virtual machine is migrated to or restarted on another virtual server.

        Note:

        High availability must be enabled both on the virtual server pool and on the guest virtual machine. If it is not enabled on both, high availability is disabled.

      • CPU Scheduling Priority: Specify the priority of a guest virtual machine to access the physical CPUs, while competing with other guest virtual machines on the same virtual server. The higher the priority, the higher the stake of the guest virtual machine in claiming CPU cycles.

      • CPU Scheduling Cap (%): Restricts the amount of physical CPU that a guest virtual machine can use. Use this to constrain guest virtual machine resource allocation.

   From: oracle.sysman.prov.agentpush.pdpShellOutEnabled=true

   To: oracle.sysman.prov.agentpush.pdpShellOutEnabled=false

   After this change has been made, you must restart the Oracle Management Service.

9.8.5 Provisioning a Guest Virtual Machine Using Oracle VM Templates

You can create one or more virtual machines by deploying a template. The deployment of the template is based on the constraints defined while the template was created. Typically, a template can contain an operating system, basic configuration (number of CPUs, memory, disk size), and preinstalled applications. The initial placement of virtual machines will be based on the storage, network and computational resources. Once a template is deployed, additional instances can be added (scale up) or removed (scale down) based on application demand.

Note:

Enterprise Manager supports deployment of legacy Oracle VM 2.2 style Templates. This templates are available in the .tgz file format. Guest virtual machines are created when these templates are deployed, but the you need to manually login to the VNC console of the newly created virtual machines to complete the network and product configuration. Also, unlike for Oracle Virtual Assemblies (.ova file format), Enterprise Manager does not automatically push the Management Agent for Oracle VM 2.2 Templates (.tgz file format).

Prerequisites

• Enterprise Manager Cloud Control is set up to manage the cloud environment.

• The template is available to the zone and you have sufficient privileges to deploy it.There are sufficient resources available in the zone for successful deployment.

9.8.7 Creating PXE Bootable Guest Virtual Machines

One of the key requirements of provisioning is the hardware server's ability to boot over the network instead of a diskette or CD-ROM. There are several ways computers can boot over a network, and Preboot Execution Environment (PXE) is one of them. PXE is an open industry standard supported by a number of hardware and software vendors. A detailed document on PXE specification can be found at http://www.pix.net/software/pxeboot/archive/pxespec.pdf.

You can create a network bootable (PXE boot) virtual machine that has the minimum configuration information, then start the virtual machine through Preboot Execution Environment (PXE) over a network later to install the guest operating system.
