11 Oracle VM Server for SPARC

Oracle Solaris VM Server for SPARC technology, formerly known as Logical Domains or LDoms, enables server virtualization on SPARC platforms. You can create and manage multiple virtual machine instances simultaneously on a single SPARC machine. Each virtual machine, or guest, can run a different operating system.

With Enterprise Manager Ops Center, you can monitor and manage all of the virtual machines from a single browser user interface. You can use virtual pool technology to maximize capacity without overloading a server. To balance the load, you can move a virtual machine from one physical system to another system either automatically or rmanually, from the user interface.

In this release you can perform the following tasks:

Provision the system to create Control Domain
Reboot, and shut down the Oracle VM Server
Monitor and interpret the performance of Oracle VM Server
Create and provision logical domains
Manage logical domains, including editing, migrating, starting, rebooting, and shutting down domains
Monitor and interpret the performance of logical domain

About Oracle VM Server for SPARC

You use hardware virtualization to create multiple virtual machines on a single piece of physical hardware. Unlike Oracle Solaris Zones, where the operating system is the same for each non-global zone, virtual machines can run on full instances of different operating systems, or different versions of the same operating system. These instances are called logical domains.

Oracle VM Server for SPARC technology, formerly known as Logical Domains or LDoms, is virtualization of SPARC servers. This technology is part of a suite of methodologies for consolidation and resource management for SPARC Chip Multi Threading (CMT) systems. This technology allows you to allocate a system's various resources, such as memory, CPU threads, and devices, into logical groupings and create multiple discrete systems. These discrete systems have their own operating system, resources, and identity within a single system. By careful architecture, an Oracle VM Server for SPARC environment can help you achieve greater resource usage, better scaling, and increased security and isolation.

When Oracle VM Server for SPARC software is installed, a domain called the control domain is created. From this control domain, you create virtual machines called logical domains that each run an independent OS. A logical domain is a virtual machine with resources, such as a boot environment, CPU threads, memory, I/O devices, and its own operating system. The control domain manages the logical domains. Each logical domain can be created, destroyed, reconfigured, and rebooted independently of other logical domains.

Oracle VM Server for SPARC functionality is especially useful in the following scenarios:

To combine several small UNIX and Linux servers, you can create logical domains to host the applications running on those servers.
To use different OS kernels in the same system, you can create logical domains to host different OS kernels.
To provide maximum isolation and security, logical domains provide separate OS and hardware resources.
To replace multiple legacy servers, set up a one-to-one mapping from legacy servers to the logical domains.

See Additional Resources for links to the Oracle VM Server for SPARC product documentation.

Enterprise Manager Ops Center and Oracle VM Server

Enterprise Manager Ops Center can manage logical domains that are created through the its user interface. When you use Enterprise Manager Ops Center to provision the Oracle VM Server for SPARC software, Enterprise Manager Ops Center installs the Oracle Solaris OS, the control domain, and an agent on the target system. This provisioning action removes existing virtualization software, including any logical domains.

Note:

You can discover logical domains that were created through the native CLI and display them in the Assets tree. However, you cannot use Enterprise Manager Ops Center to perform any actions on those domains.

Requirements for Oracle VM Server for SPARC

Enterprise Manager Ops Center supports Oracle VM Server for SPARC 1.2, 1.3, 2.0, and 2.1 version. The Oracle VM Server must meet specific hardware, OS, and firmware requirements.

Note:

The OS in the control domain must have the default locale set to C. The control domain provisioning is supported on Oracle SPARC or x86 Proxy Controllers, but not on Linux Proxy Controllers.

Note:

To provision the Oracle VM Server for SPARC software, the proper system model name must be populated on the service processor. The model name is not available on the service processor of the Sun Blade T6320 hardware.

Architecture of Oracle VM Server for SPARC

Figure 11-1 shows a sample architecture that contains a control domain and three logical domains. The system administrator created a logical domain for different areas of company. The first domain deploys a financial application; the second domain deploys a database application; the third domain deploys a web application. CPU threads and memory resources are assigned to each domains, depending on the requirements.

Figure 11-1 Sample Architecture for Oracle VM Server for SPARC

Description of "Figure 11-1 Sample Architecture for Oracle VM Server for SPARC"

The control domain handles the Oracle VM Server environment and creates the logical domains. The hypervisor is a firmware layer on the FLash PROM of the motherboard, operating between the OS and the hardware. The hypervisor provides a set of support functions to the OS, so that the OS does not need to call hardware functions.

Roles for Domains

Oracle VM Server for SPARC software's control domain, or virtual host, createw and manages the logical domains and allocates virtual resources to other domains. In addition to control domains and logical domains, the software can create domains for specific roles, such as a service domain and an IO domain.

An individual domain can have one or more of these roles, such as combining the functions of an I/O and service domain. In Enterprise Manager Ops Center, the control, service, and I/O domains are in the same domain.

Control Domain

The Oracle VM Server virtual host runs in the control domain. There can be only one control domain for each server. The first domain created after installing the Oracle VM Server software is the control domain and is named the primary domain. The control domain contains the SUNWldm packages, including the Oracle VM Server host application and the host daemon (ldmd) process required for managing logical domains. If you have an OS and other software running on a server and you install the Oracle VM Server software, that server becomes your control domain.

Note:
Zones are not supported in the control domain. You must not run user applications in the control domain and you cannot migrate, delete, or shut down a control domain.
Logical Domain

The logical domain is a complete virtualized environment that has no ownership of physical I/O or virtual devices. This domain is managed by the control domain and uses services from the I/O and service domains. The logical domain must run an OS that supports both the sun4v platform and the virtual devices presented by the hypervisor.
Service Domain

The service domain provides virtual device services such as a virtual network switch, a virtual console concentrator, or a virtual disk service, to other domains.
I/O Domain

The I/O domain has direct access to physical I/O devices, such as a network card in a PCI Express controller. This domain shares the devices with others in the form of virtual devices when the I/O domain is also the control domain. The number of I/O domains that you can have depends on your platform architecture. For example, if you are using an UltraSPARC T1 processor, you can have a maximum of two I/O domains, with one of them being the control domain.

Configuration for an Oracle VM Server for SPARC

To install Oracle VM Server for SPARC software, apply a profile that specifies the values for resources such as CPU threads, crypto units, and memory as described in Creating an OS Profile for Oracle VM Server.

Note:

Enterprise Manager Ops Center does not support use of the LDoms configuration manager in LDoms 1.2. Do not attempt to reconfigure the control domain and logical domains using the native CLI of Logical Domain software.

The recommended minimum configurations for the control domain are described in the following sections.

CPU Threads

The number of system CPUs determines the number of control domain CPU threads:

For less than 16 system CPUs, set the control domain CPU Threads to 2.
For between 16 and 64 system CPUs, set the control domain CPU Threads to 4.
For more than 64 system CPUs, set the control domain CPU Threads to 8.

Crypto Units

Crypto units are the resources on the supported platforms that provide high-performance, dedicated cryptographic engines. These can be used for tasks such as encrypting and decrypting network traffic between a Secure Socket Layer (SSL) web server and an application server.

Each CPU core has one crypto unit and four or eight CPU threads. Because the crypto unit is part of a core, the crypto unit is bound only to domains that contains at least one thread from the parent core. Crypto units cannot be split as CPU threads are. For example, you have assigned the crypto unit for the first CPU core to the control domain. If a new logical domain is assigned a thread from the first CPU core and the crypto unit for that core is already assigned, the control domain cannot assign that crypto unit to the new logical domain. Allocation of crypto units might not succeed, especially if a core is split between domains. An Oracle VM Server might allocate fewer crypto units or none at all.

You must assign at least one crypto unit to the control domain because the crypto unit enables domain migration.

Example 11-1 Example of Crypto Unit Assignments

In UltraSPARC T1 based servers, one core is four CPU threads. Therefore, assign one crypto unit and four CPU threads to the control domain. These values are set in the OS profile for Oracle VM Server for SPARC.

In UltraSPARC T2 and T2 Plus based servers, one core is eight CPU threads. Therefore, assign one crypto unit and eight CPU threads to the control domain.

RAM

The amount of RAM for the control domain depends on the size of the system RAM::

For system RAM less than 8 GB, set the control domain's RAM to 1 GB.
For system RAM between 8 GB to 16 GB, set the control domain's RAM to 2 GB.
For system RAM greater than 64 GB, set th econtrol domain's RAM to 8 GB.

Additional Configurations

The following configuration for the control domain is performed during installation of Oracle VM Server for SPARC and does not need to be included in the profile:

A virtual network switch for each subnet named subnet-address_prefix-length, for example, 10.17.7.0_24
A virtual disk server named primary-vds0
A virtual console concentrator is named primary-vcc0

Creating an OS Profile for Oracle VM Server

Create a profile to install the Oracle VM Server for SPARC software, the OS, and to set the parameters for the control domain. Use this profile in a deployment plan that provisions a SPARC server's service processor.

Note:

The version of Oracle VM Server for SPARC to be installed depends on the target systems. After the provisioning job starts, an information problem displays the version that is installed on the target server.

Provisioning Oracle VM Server for SPARC

You can install the software on bare-metal or on systems that is already configured with logical domains. When you provision Oracle VM Server through Enterprise Manager Ops Center, any previous configuration is removed from the service processor by resetting the service processor to its factory defaults.

When you provision Oracle VM Server for SPARC, the instance of the Oracle Solaris OS becomes the Control Domain which is the first domain to be created. The virtual host on which this instance of Oracle Solaris OS runs is called the Oracle VM Server Host or simply, Oracle VM Server. The Logical Domains Manager runs in the control domain to create and manage logical domains. You can have only one control domain per server. You cannot change the name or destroy the control domain.

This section describes how to install the Oracle VM Server for SPARC software on a service processor.

The Oracle VM Server for SPARC provisioning job performs the following major tasks:

Downloads the appropriate OS image.
Initiates a net boot action on the Service Processor.
Configures DHCP and installs the OS.
Installs the Oracle VM Server Host.
Configures Oracle VM Server Host according to the values set in the profile such as memory, CPU threads, Crypto units, and virtual console port range.
Depending on the version, installs the SUNWJass package to harden the system.
Enables the Fibre Channel ports on the system that is configured for storage.
Installs and configures the agent. Do not install the agent manually on the Oracle VM Server host.

Before You Begin

The Oracle VM Server for SPARC software depends on particular Oracle Solaris OS versions, required software patches, and particular versions of system firmware. See Requirements for Oracle VM Server for SPARC .
Discover the target system on which you want to install Oracle VM Server for SPARC software.
Configure DHCP services on Proxy Controllers. See CONFIGURING DHCP.
Create a profile for provisioning Oracle VM Server for SPARC. See Creating an OS Profile for Oracle VM Server.
Create a deployment plan with the profile created for provisioning Oracle VM Server for SPARC.

See Deployment Plans for information about creating a plan with this profile .
(Optional) Adjust the amount of time allowed for the job. The default time is three hours.
1. In the Enterprise Controller, edit the /var/opt/sun/xvm/satellite.properties file and locate the osp.default_timeout property.
```
OS Provisioning
##################################
# Default Timeout of OSP Job
osp.default_timeout=180
```
2. Change the value of the property to the desired number of minutes.
3. Save and close the file. You must restart the Enterprise Controller after changing the value.
The Oracle VM Server for SPARC version to be provisioned is selected depending on the type of target server and firmware version. You can define the version to be provisioned explicitly. The version value is read during the provisioning job.
1. In the Enterprise Controller, edit the /var/opt/sun/xvm/satellite.properties file.
2. Add the following entry with one of the valid versions: 1.2, 1.3, 2.0, and 2.1.
```
osp.ldom_version=<version>
```
3. Save and close the file. You do not need to restart the Enterprise Controller.
  
  To allow Enterprise Controller to determine the proper version of Oracle VM Server, edit the properties file and remove this entry.

To Apply the Profile on the Target

You apply a profile to a target system by applying a deployment plan that contains the profile. The plan can contain other profiles too. You can apply the Oracle VM Server provisioning profile in one of the following ways:

Method 1: Select the Target

Select the server that will become the Oracle VM Server host from the Assets sections.

If you chose to override profile values, select options and edit the parameters for each step in the wizard. If you chose minimal user interaction option, you specify the resources.
Specify the network resources for each target.
Enter the IP address for each target.
Review the summary of the parameters for provisioning the Oracle VM Server.
Click Apply the deployment plan on the selected targets.

Initiating Manual Net Boot

A target system requires a manual net boot operation if Enterprise Manager Ops Center cannot perform a remote network boot process. Profiles that provision this type of system contain the Manual Net Boot option. You must initiate the net boot operation when the Oracle VM Server provisioning job is completed.

Log in to the service processor of the target system.
If the target system is running, enter halt.
Enter the following command
```
boot net:dhcp - install
```

Provisioning the Oracle VM Server Version

The version of Oracle VM Server for SPARC software installed on the target server is determined during the execution of the job, unless you have defined the version explicitly. The version installed depends on the following conditions:

If the target is a T1 server, the Oracle VM Server for SPARC 1.2 version is installed. The Oracle VM Server SPARC versions 1.3 and 2.0 are not supported for T1 servers.
The system-firmware versions also determines the version of Oracle VM Server for SPARC that is installed.
- For Firmware 7.1.x , Oracle VM Server for SPARC 1.2 is installed.
- For Firmware 7.2.0 to 7.2.6 , Oracle VM Server for SPARC 1.3 is installed.
- For Firmware 8.0Firmware 7.4.0 on UltraSPARC T2 and UltraSPARC T2 Plus Servers – Oracle VM Server for SPARC 2.1.0 or higher , Oracle VM Server for SPARC 2.0 is installed.
- Firmware 8.1.0 on SPARC T3 Servers – Oracle VM Server for SPARC 2.1.
The JASS that is used for hardening the system does not apply to Oracle VM Server for SPARC 1.3 and 2.0 versions. If you have selected the Enable JASS option, the option is skipped when installing Oracle VM Server for SPARC 1.3, 2.0, and 2.1 versions. A notification is sent if this even occurs.

Creating Logical Domains

A logical domain is a virtual machine that has its own operating system and identity within a single server. Each logical domain can be created, destroyed, reconfigured, and rebooted independently, without requiring the server to be powered off. You can run a variety of applications in different logical domains to keep them independent for performance and security purposes.

Enterprise Manager Ops Center can create logical domains and install Oracle Solaris OS on them. Using profiles and deployment plans, you can to create more than one domain simultaneously and then save the configuration for future logical domains.

To create logical domains:

Create Logical Domain Profile and Plan – You create a profile which defines the configuration of the logical domain. Using the profile, you create a deployment plan. You apply the plan on an Oracle VM Server to create logical domains. The logical domains do not have the Oracle Solaris OS. You then select each logical domain and apply an OS provisioning plan to install the OS. See Provisioning Logical Domains for provisioning OS on the logical domains.
Configure and Install Logical Domains – This is a complex plan which contains deployment plans that create logical domains and install Oracle Solaris OS on them. You must have the required profiles and deployment plans available to create the complex plan..

Creating Logical Domain Profiles

A logical domain profile contains the requirements and configuration for an entire logical domain, including the CPU Threads, memory, storage, and network details . When a deployment plan applies the profile, you create a logical domain. You must provision Oracle Solaris OS on each domain separately. As an alternative, you can include the logical domain profile along with an OS provisioning profile in a complex plan.

See Logical Domain Profiles for detailed procedures for creating logical domain profiles and plans.

Provisioning Logical Domains

After you create a logical domain, you must provision an OS.

Ensure that you have imported the appropriate Solaris 10 (at least Solaris 10 8/07) ISO image into the library.
Create or identify an OS provisioning profile for SPARC. See Creating an OS Profile for Oracle VM Server.
Create or identify a deployment plan with the OS provisioning profile.

To Provision a Logical Domain

Select a logical domain from the Assets in the Navigation pane.
Select Install Server in the Actions pane. The Install Server window is displayed with the list of deployment plans for logical domains. If no plans are listed, click Create New Plan to create an OS provisioning plan. See Creating an OS Profile for Oracle VM Serverto create a plan.
Select an available plan from the list.
Select whether you want to apply the plan with minimal user interaction or override any profile values.
Click Apply Plan. The Provision OS wizard launches. You can apply the plan in the following methods:
- Minimal user interaction – All the OS provisioning configuration values are applied but you are prompted to enter the network resource assignment such as the IP address of the system. Enter the IP address and click Next.
- Override profile values – You apply each configuration value in the profile. Accept or change the values and then click Next.
Review the information in the Summary step and click Apply to install the OS on the logical domain.

Starting a Logical Domain

To start a logical domain, you must select a stand-alone Oracle VM Server or virtual pool that has sufficient resources to host the logical domain. When you start a logical domain, the logical domain is powered on and the OS is booted.You can change the following during the start process:

Virtual pool wher e the Oracle VM Server resides
Oracle VM Server host of the logical domain
Network used by the logical domain

To Start a Logical Domain

Select the logical domain that you want to start from the Assets section of the Navigation pane.
Select Start Guest from the Actions pane. The Start Guest wizard is displayed.
Select the virtual pool in which you want the logical domain to run. Click Next.

Note:
If any network is assigned to the logical domain but not associated with the virtual pool, the network is not available after the logical domain starts.
Select the Oracle VM Server that is the host for the logical domain or choose a different Oracle VM Server. You can view the load of each Oracle VM Servers and select an Oracle VM Server from the table. Click Next.
Specify the network interfaces for the logical domain. Specify the virtual switch that connects to the logical domain's MAC address. You cannot connect the same virtual switch to two different MAC addresses

(Optional) You can select Do Not Connect if you do not want a connect a logical domain MAC address to any virtual switch.

Click Next .
Choose whether to start the logical domain immediately or to specify the date and time to start. Click Next.
Review the selected parameters and click Start to start the logical domain. A job is submitted to start the logical domain.

Managing Logical Domain Networks

You can connect to a logical domain to a network multiple times on the same Oracle VM Server. For each connection, a virtual switch is created in the Oracle VM Server but you must specify the NIC each virtual switch uses. This association is done when attaching networks to Oracle VM Server.

You can now create IPMP groups in logical domains manually. It takes approximately 15 minutes for a new IPMP group to display in the UI.

You can also aggregate the NICs for the logical domain and create an aggegated link.

See About IPMP Groups and Aggregated Links for information about IPMP and link aggregation support in Enterprise Manager Ops Center. For more information about creating IPMP and link aggregations, see Additional Resources.

To Connect a Logical Domain to a Network

Select a logical domain that is in shutdown state in the Assets section of the Navigation pane.
Click Connect Guest to Network in the Action pane. The Connect Guests to Network window is displayed. The networks that are not currently connected to the selected logical domain are displayed in the table.
Select a network that you want to connect to the logical domain. Use Shift and Ctrl keys to select more than one network.
Click Connect to Network. The selected network is connected to the logical domain

To Disconnect a Logical Domain from a Network

Select a logical domain that is in shutdown state in the Assets section of the Navigation pane.
Select the Network tab in the center pane. The list of connected networks are listed.
Select the network that you want to unbind.
Click the Disconnect Selected Guest From Network icon. The Unbind a Network window is displayed.
Select the network from the list.
Click Disconnect From Network to unbind the network from the logical domain. The selected network is disconnected from the logical domain.

Migrating a Logical Domain

You can migrate a logical domain from an Oracle VM Server to another virtual host within the same virtual pool. This type of migration is called warm migration. The logical domain is shut down or suspended and then its static configuration is moved to the target host. The logical domain is then restarted on the target host using the same virtual image. Warm migration does not maintain the live run state of the operating system, that is, going through a save-to-disk cycle during the migration. Shared storage is required for this implementation.

Before You Begin

Verify that the source and target hosts are in the same virtual pool.
Verify that the source and target hosts are in the same network.
Verify that the source and target host have access to the storage library, that is, the disk image or guest metadata, for the logical domain .
For Oracle VM Server for SPARC 1.2 version, you can migrate with only 1 MAU.

For Oracle VM Server for SPARC 1.3 and 2.0 versions, you can migrate with any number of MAUs.
Verify that the target host has sufficient resources (CPU threads, memory) ato support the logical domain.

Note:

For Oracle VM Server for SPARC 2.1, you cannot migrate a logical domain to a previous version of the server such as 2.0, 1.3 or 1.2. You can migrate only within the same version of Oracle VM Server for SPARC.

To Migrate a Logical Domain

Select the logical domain from the Assets section of the Navigation pane.
Click Migrate Guest in the Actions pane.. The Migrate Logical Domain wizard is displayed.
Select the target Oracle VM Server, the new host of the logical domain. The eligible target Oracle VM Servers is displayed in order of decreasing preference. Click Next.
