Friday Spotlight: Adopting Oracle VM Manager for Oracle VM Server for SPARC guests

Customers using Oracle VM Server for SPARC (formerly called 'logical domains') are increasingly looking at Oracle VM Manager to provide a unified management platform with Oracle VM Server for x86.  While most customers use Oracle VM Server for SPARC's native command line interface or Oracle Enterprise Manager Ops Center, Oracle VM Manager provides

  • a management solution focused on Oracle VM virtualization supporting server pools, advanced VM life-cycle and policy management, and control over the networks and storage they depend on.
  • a graphical user interface, command line interface, and API common to Oracle VM on the x86 and SPARC platforms. Administrators can use the same interactions to control servers, VMs, networks and storage on both platforms from a single screen.

The natural question is how to move existing Oracle VM Server for SPARC guests domains (virtual machines) and servers to Oracle VM Manager for their existing guests.  There is no direct way to "adopt" existing servers and VMs, but there are ways to move them to Oracle VM Manager control.

The first step is to set up at least one SPARC server in an Oracle VM Manager server pool - more servers can be added later. Guest domains can be individually moved to the server pool. This is a "cold" process (guests must be down while being moved) and applies only to guest domains (domains using physical I/O like SR-IOV cannot be moved).  Optionally, servers can be redeployed under Oracle VM Manager as capacity requirements shift from the original deployment to the new pool.

The main consideration for moving a guest is storage. Virtual disks may be on SAN LUNs (typical for production use), physical disks, ZFS volumes, or files in a file system. Oracle VM Manager supports LUNs defined as "physical disks" presented from storage arrays, so moving those virtual disks is straightforward. If virtual disks are ZFS volumes or files they must be copied to storage under Oracle VM Manager control, typically an NFS-based Oracle VM repository. File-based virtual disk images are easy to import using the Oracle VM user interface. If the virtual disks are based on ZFS volumes or internal disks, use the 'dd' command to create virtual disk images that can be imported. (The virtual disks should not be in use while being copied). 

An optimization can be used for guest ZFS pools. Make the ZFS pool a mirror using a new virtual disk of equal size as ones already in the pool, Wait for the pool to resilver, and then 'zpool split' the new virtual disk from the pool, and upload the image file into Oracle VM Manager. The advantage is that resilvering copies only "in use" disk blocks, not residual erased data, so the resulting disk image may be substantially smaller.

Whichever method is used, customers already using Oracle VM Server for SPARC may further benefit from moving to Oracle VM Manager.

Friday Spotlight: Secrets of Storage Repositories with Oracle VM

Here is some insider information for those using Oracle VM. 

You use repositories in Oracle VM to store virtual resources such as ISO files, virtual disks and assemblies. Indeed you must have at least one repository to store the configuration files of your virtual machines.

Creating and populating your Oracle VM repositories is straightforward. Relocating repositories is a bit more involved.

You might want to answer the following questions:

  • Can you move an existing repository between server pools in your Oracle VM environment?
  • What happens to your repositories if you reinstall the Oracle VM Manager software?
  • Did your Oracle VM environment retain the UUID of the Oracle VM Manager from your previous environment
  • When building your recovery site as part of disaster-recovery operations do you have a plan to reclaim any repositories that were active in the failed environment
  • Could you get comprehensive answers to all these questions in 30 minutes

To answer these questions, you can view this series of 6 demos. You will learn the steps to reclaim your repositories. The first 4 demos introduce concepts that are important when relocating repositories. Demos 5 and 6 present practice scenarios where reclaiming repositories is a critical step for recovering virtual resources.

If the information in these demos is of use to you, you could consider taking the following courses:

You can take these courses by traveling to an education center as an in-class offering or from your own desk as a live-virtual offering.

Friday Spotlight: Oracle VM Server for SPARC 3.2 features

For this week's Friday spotlight, I want to highlight the improvements in live migration and virtual disk multipathin which were delivered as part of Oracle VM Server for SPARC 3.2 released in March 2015. 

  • Provide live migration performance enhancements, including parallel memory-mapped I/O and optimized firmware copying routines. These enhancements reduce the overall migration time and the time during which the migrated guest domain is suspended. 
  • Update virtual disk management for mpgroups to show and specify the selected path to the virtual disk backend. You can see the path that is currently used and dynamically request a path switch.

To learn more details about enhanced features please see the blog entries on live migration improvements and on disk multipathing.

Friday Spotlight: Oracle VM Server for SPARC certification for Oracle RAC 12cR1 with Oracle Clusterware, and tips on SPARC server configuration

Oracle RAC 12cR1 (12.1.0.2) with Oracle Clusterware (12.1.0.2)  is now certified on Oracle VM Server for SPARC with Oracle Solaris 11 guest domains. Visit http://www.oracle.com/technetwork/database/virtualizationmatrix-172995.html for details.

Also, two technical notes for Oracle VM Server for SPARC users configuring root domains on SPARC T5-2, SPARC M5-32, and SPARC M6-32 servers for resiliency. Please see My Oracle Support note Doc ID 1948940.1 for SPARC T5-2, and Doc ID 1942045.1 for SPARC M5-32 and SPARC M6-32 on details for PCI bus assignment requirements for Fault Management Architecture (FMA) fault proxying.
