Next week, IOUG will be hosting a Virtualization Online Symposium on Oracle VM. It is an all day event from 10:00am-2:50pm CST. I will be giving a webinar discussing how to maximize your virtualized environment with Oracle VM @11:00am-11:50am CST. If your interested, feel free to register and listen in! I’ll be taking questions after the session
The IOUG Events page can be found here: http://www.ioug.org/p/cm/ld/fid=89

For those of you that are installing OVM Manager 3.x, I wanted to point out that Oracle provides a shell script found within the OVM Manager ISO called createOracle.sh which will create the appropriate oracle user and groups and set the environment for a successful OVM Manager installation. Make sure to take advantage of it to make your installation that much easier!
Today’s tip is more of asking you the reader’s out there on what type of content you’d like to see on my blog with regards to OVM. Don’t be afraid to post a comment and I’d be more than happy to address those questions
Hope to hear from you all soon!
I just wanted to give you a heads up that the latest OVM Manager 3.1.1 patch is available for download. A snippet below from Oracle’s release notes of what to expect from this patch.
Oracle VM 3.1.1 Manager patch is available at My Oracle Support (reference patch number 14227416)
Please review the README for a complete list of bug fixes as well as the instructions to apply the patch update.
Description of Changes:
- 14697223 - Adds check for network port value, prevents a null pointer exception from being thrown.
- 14657062 - This change will prevent users from presenting a storage repository to a server not in the file server's admin server list.
- 14253137 - Improves the handling of slave ports with differing MTU settings during bond creation.
- 14600223 - Fixes the issue where during discovery of a server mounts from file servers that do not have that server in its admin server list, were tried to be discovered.
- 14350980 - Fixes the issue where the virtual network interfaces got reordered according to alphanumeric sorting of MAC address.
Oracle has released Oracle VM 3.2.1 BETA and Oracle VM Manager 3.2.1 BETA. It can be accessed via http://www.oracle.com/technetwork/server-storage/vm/downloads/ovm-early-access-1743261.html
From the link above, these are some of the new features and enhancements to expect:
What’s New in Oracle VM 3.2.1 Beta
The new features and enhancements in Oracle VM Release 3.2.1 Beta include:
- Support for Oracle VM Server for SPARC: Oracle VM Manager can now be used to discover SPARC T-Series servers running Oracle VM Server for SPARC, and perform virtual machine life cycle management.
- Oracle VM Command Line Interface (CLI): The new Oracle VM Command Line Interface can be used to perform the same functions as the Oracle VM Manager Web Interface, such as managing all your server pools, servers and guests. The CLI commands can be scripted and run in conjunction with the Web Interface, thus bringing more flexibility to help you deploy and manage an Oracle VM environment. See the Oracle VM Command Line Interface User’s Guide for information on using the CLI.
- Usability Improvements: There are a number of enhancements to help improve user experience when using Oracle VM Manager, such as configuring the accessibility options, monitoring the overall health and status of your server virtualization environment with health tab, multi-select of objects, search for objects, the ability to present repository to server pools in addition to individual servers, rediscovering all Oracle VM servers, setting preferences for recurring jobs, and setting UI timeout.
- Updated Dom0 Kernel in Oracle VM Server for x86: The Dom0 kernel in Oracle VM Server for x86 has been updated so that it is now the same Oracle Unbreakable Enterprise Kernel 2 (UEK2) as used in Oracle Linux, for complete binary compatibility with drivers supported in Oracle Linux.
- MySQL Database Support: MySQL Database is used as the bundled database for the Oracle VM Manager management repository for simple installations. Support for an existing Oracle Database is still included within the installer so that you can perform a custom installation to take advantage of your existing infrastructure.
Today I wanted to quickly touch on Anti Affinity groups. Essentially, anti affinity groups ensure that a set of VMs will not run on the same OVM server. Why is this important? Well for instance, if your running Oracle RAC on your VMs, you’d want to ensure those instances are not on the same OVM Server to ensure high availability. How do I set anti affinity groups up? Glad you asked!
To create an anti-affinity group:
Select Servers and VMs tab ->from the Perspective dropdown on the management pane select Anti-Affinity Group. Select the + icon to create a new Anti Affinity Group.
When the dialog box opens, appropriately assign a name to your anti affinity group, and click Next.
Then Select the appropriate VMs that you want to ensure never run on the same OVM Server, and move them over to the Selected Virtual Machines section and click Finish.
Now you have ensured those VMs will not run on the same OVM Server! Until next time! Hope you enjoyed the tip.
Today I finished my first session about Oracle VM 3 at Oracle World 2012! For those of you interested, I’ve decided to post the PPT in PDF format on my site Hope you enjoy! In the coming weeks, I plan on touching on those different subjects but if your eager feel free to check out the PDF
In today’s topic, I’d like to discuss the process of backing up and restoring your Oracle VM Manager. Since the Oracle VM Manager is used to manage all your virtual machines and virtual machine resources, I thought it would be a good exercise to discuss the step-by-step process on backing up and restoring the OVM Manager environment. It is crucial to make backups of your Oracle VM Manager to ensure that you don’t lose any data from the Oracle VM Manager repository database that could cause you a headache in having to actively restore each virtual machine to a new Oracle VM Manager, one by one (not a fun exercise). The good news is Oracle has made the backup-restore process quite easy. In the example below, I will be backing up my original Oracle VM Manager, and restoring the content from my old server it into a new server all that has a fresh install of Oracle VM Manager.

One of the tougher aspects of Oracle VM is deciphering how to debug errors found in the logs within the Oracle VM Manager. Today I’d like to discuss an issue I’ve come across when trying to create a server pool within the Oracle VM Manager. The bug specifically consisted of my Oracle VM Manager not correctly entering the proper IP information within the /etc/hosts file of my Oracle VM Server host.
