Friday Spotlight: Integrating Oracle VM with Oracle OpenStack for Oracle Linux

Oracle’s contribution and participation in Docker and OpenStack bring more flexibility and openness to Oracle VM deployment. Customers can take advantage of Oracle VM 3.4 and Oracle OpenStack for Oracle Linux 2.1 when building an open cloud infrastructure

Oracle VM Server for x86 incorporates an open source Xen hypervisor component, which has been customized and optimized as a virtualization and management solution for x86 servers. The libvirt driver is part of Oracle VM Server 3.4 to integrate with OpenStack. On an Oracle VM Server based compute node, the native libvirt driver is used (libvirt is not run in a container). All other OpenStack compute node services are run in Docker containers on Dom0.

The Dom0 kernel of Oracle VM Server 3.4 has been updated to Oracle Unbreakable Enterprise Kernel (UEK) Release 4, based on the 4.1 mainline kernel, not only to enable Docker container deployment, but also to bring performance improvements and rapid driver availability and streamlined partner certifications with Oracle Linux.

To get started, refer to the Installation and Deployment Guide and Release notes.

Friday Spotlight - Oracle VM 3.4 Dom0 Enhancements

This is another blog in the series to give the Oracle VM community some additional information on the 3.4 release that we announced on March 24. This week, we are going to share a little more information on the Dom0 kernel enhancements that were delivered with this updated version of Oracle VM..

Modern Dom0 kernel

With Oracle VM 3.4 we updated the Dom0 kernel to Oracle Unbreakable Enterprise Kernel (UEK) Release 4, based on the 4.1 mainline kernel. This update brings performance improvements; and rapid driver availability and streamlined partner certifications with Oracle Linux and Oracle VM. The latest set of driver updates offered with this new kernel can be found in the Release Note for UEK Release 4.

Dom0 kernel updates on live systems

Ksplice updates for the Dom0 kernel used on Oracle VM 3.3 (UEK3) and Oracle VM 3.4 (UEK4) are now available. All Oracle VM customers with Premier Support for their x86 Servers will be able to access the Ksplice channel on ULN to take advantage of this Oracle technology to add important kernel updates and security patches without needing to live migrate VMs or reboot your Oracle VM Server.

The process to install the Ksplice Uptrack client and perform the live kernel updates is similar to the process for Oracle Linux since this is used for the Dom0 user space in Oracle VM. Please refer to the KM note on My Oracle Support for all the information you need to use Ksplice with your Oracle VM deployment. The document “Oracle VM: Using Ksplice Uptrack” can be found with Doc ID 2115501.1.

  • 62% quicker navigation between tabs
  • 66% faster response to actions like expanding the Server Pools folder

The net result is quicker response times when you perform jobs with the Manager which results in more time to focus on other IT tasks in your data center. Early feedback from an early adopter of Oracle VM 3.4 claims “It’s so zippy!”

Oracle VM Server:

With the introduction of an updated version of the Xen hypervisor and additional enhancements made to the Oracle VM Server code, the 3.4 release offers higher levels of scalability and performance:

  • Capacity increases:

    • CPUs per host Server increased to 384

    • vCPUs per VM increased to 256

    • VM vDisk size increased to 10TB (NFS) and 64TB (OCFS2)

    • VMs per host Server increased to 300

  • Faster live migrations – internal testing shows a 4x improvement in a typical migration time.

Oracle VM Agent for SPARC:

Improvements made to the Oracle VM Agent for SPARC have resulted in a 4x decrease in discovery time for a T5-8 in a customer deployment.

Oracle VM is engineered for the Open Cloud Infrastructure to increase datacenter flexibility, meet your price/performance needs, and make applications easier to deploy, manage, and support.

For more Information - Oracle VM 3.4 documentation is available on the Oracle Technology Network (OTN)
