Oracle VM Templates now available on SPARC platforms

Oracle VM Templates provide an innovative approach to deploying a fully configured software stack by offering pre-installed and pre-configured software images. Use of Oracle VM Templates eliminates the installation and configuration costs, and reduces the ongoing maintenance costs helping organizations achieve faster time to market and lower cost of operations. Customers have been enjoying the benefits of accelerating software deployment with Oracle VM Templates on x86 platforms. Now we have made Oracle VM Templates available when deployed with Oracle VM Server for SPARC.

Oracle VM Manager 3.2 introduced the ability to discover SPARC servers running Oracle VM Server for SPARC, and perform virtual machine operation tasks - just the same experience as Oracle VM Server for x86. Thus you can take full advantage of Oracle VM Templates.

To create a virtual machine from an imported template / assembly. You download an Oracle VM template that contains an assembly file (.ovf file), and importing it into Oracle VM Manager as an assembly, then creating a template from the assembly. You can read the related documentation: Creating a Virtual Machine and the white paper: Oracle VM Manager 3.2: Quick Start Guide for Managing Oracle VM Server for SPARC (PDF).

1) Download Oracle VM Templates

  • Visit Oracle Software Delivery Cloud 
  • Complete your registration information (Name, Company Name, Email Address and Country) and click on the download agreement
  • Select "Oracle VM Templates" from the "Select a Product Pack" pull-down menu
  • Select "SPARC" from the "Platform" pull-down menu
  • Download and unzip the files and read the readme

2) Place the downloaded Oracle VM Template into a location where it's accessible by Oracle VM Manager using HTTP, HTTPS or FTP. After logging into Oracle VM Manager 3.2, click Repositories tab, identify the repository to use and select Assemblies. Then click the icon to import an Assembly. After a few minutes (depending on the network / server speed),  the assembly would be imported then.

3) Create a VM Template from the Imported Assembly - Select the imported assembly, then click the icon "Create VM Template ...". After a few minutes, depending on the server/storage configuration, a VM template is now created.

4) Edit VM template - you can edit the VM template to verify the general setting, such as the network setting.

5) Clone a VM from the Template - Next it's to clone a virtual machine from the newly created template.You click the icon "Clone or Move Template ..."

6) Start the VM - After the VM is cloned, it is placed under the server pool (defined in the target server pool option when cloning the template) and the VM status is "stopped". Then start the VM, and it's ready to use.

7) After the VM is started, you can access the VM serial console by clicking the "Launch Serial Console" icon. You need to go through the initial Solaris configuration if it is the first time to start the VM, for example, to configure the network, hostname, time zone, user name, and so on. Serial console access works for both x86 and SPARC based virtual machines. For additional options of accessing the guest VM console, such as VNC based console access for x86 virtual machines, read the user guide: Connecting to a Virtual Machine.

Optimize Workload Performance on SPARC T4 Systems with Oracle VM Server for SPARC

Early this week Oracle launched SPARC T4 Servers and SPARC SuperCluster T4-4. With Oracle VM Server for SPARC, the built-in server virtualization solution on SPARC T-Series systems, you can use dynamic CPU threading controls to optimize workload performance on SPARC T4 systems.

These threading controls enable you to specify the number of hardware threads to be activated per core. CPU performance can be optimized for CPU-bound workloads by tuning CPU cores to maximize the number of instructions per cycle (IPC). Or, CPU performance can be optimized for maximum throughput by tuning CPU cores to use a maximum number of CPU threads. Existing applications can take advantage of the SPARC dynamic threading performance benefits without having to be rewritten or recompiled.

To learn how to use CPU threading controls to optimize CPU performance on SPARC T4 platforms,  read the white paper:
