I’m sure everyone from time to time has had to open up a Service Request (SR) with Oracle regarding Oracle VM. One of the biggest tips I can give you so that you don’t lose hours awaiting a response that just reports “Hi, <name>, can you please provide the following logs. – X.log” is send them the logs they already need as you are opening the SR. How do you do this? Well it is easy! If you follow the My Oracle Support (MOS) Document: VMPinfo3 Diagnostic Capture for Oracle VM 3 troubleshooting [ID 1364933.1] you can beat them to the punch! All you need to do is download and install vmpinfo-sos-report rpm for all your Oracle VM Servers and the vmpinfo-manager rpm for the Oracle VM Manager (rpms provided in the VMPinfo3 MOS document). Once installed, log in to the Oracle VM Manager and run the vmpinfo3.sh shell script with the appropriate options as mentioned in the My Oracle Support Document and upload the vmpinfo3-<date-time>.tar.bz2 found under the /tmp directory on your Oracle VM Manager. This small tip can save you quite some time when getting any Oracle VM issue resolved.
Oracle VM 3.2.1 is officially out and available for download at http://edelivery.oracle.com
I’ll be posting soon on highlighting some of the key features found with this new release. In the mean time, feel free to play with the new version and send any questions you might have or would like me to test/talk about in the next blog.
Update: More info can be found here on the release: http://www.oracle.com/us/corporate/press/1899105
There are two patches available for OVM Server 3.1.1 + OVM Manager 3.1.1. The Patch ID for the OVM Server is 14775391, while the Patch ID for the OVM Manager is 14227416.
Release notes for the Oracle VM Manager:
The patch update can be downloaded from My Oracle Support, patch ID 14227416.
New patch update provides additional bug fixes, and includes all the accumulative bug fixes delivered in the previous patch updates.
Oracle VM Manager 3.1.1 Build 544
Oracle VM Manager 3.1.1-544 has been validated in combination with Oracle VM Server 3.1.1-524
Bugs fixed in Oracle VM Manager 3.1.1-544 are:
- 15924190 – Fixes the issue that it leaves jobs in a bad state when refreshing browser with open jobs. In addition, when the user closes a browser tab or the entire browser with open jobs, the session will be validated by the WebLogic server in the specified timeout value (default 30 minutes). So any pending jobs will be aborted at that time.
- 15878716 – Fixes the issue that caused Oracle VM Manager HTTPS connections to fail with Microsoft Internet Explorer 7, 8, and 9 after applying the recent security update. Please review the Oracle VM Manager Upgrade Instructions section below for post-upgrade commands.
- 15864022 – Adds support for dynamically changing the cluster store cache size. The default cache size is now 150K.
- 15827070 – Fixes the “Object Not Found” issue when hitting the Escape button in the VLAN dialog box.
Oracle VM Server 3.1.1 Build 524
Oracle VM Server 3.1.1 build 524 has been validated with Oracle VM Manager 3.1.1 build 544.
The following RPMs have been updated:
I thought today, I’d share a link to a great article called Looking “Under the Hood” at Networking in Oracle VM Server for x86. It shows how the underlying framework works and for those of you interested in learning a little more about OVM and it’s Networking a good place to start
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
Registration can be done here: https://www1.gotomeeting.com/register/675373441
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)

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.

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.
Yesterday I introduced one of OVM’s feature called Distributed Resource Scheduling (DRS). Today I’m going to talk a little bit about Distributed Power Management (DPM). DPM was introduced to provide a way to consolidate VMs into the fewest amount of OVM servers while being able to turn off OVM servers that are not actively running VMs to conserve power. DPM is policy driven just like DRS, it runs a job based on the time interval provided when setting DPM. So how does it work? Well DPM monitors your CPU utilization and if a certain threshold is met it will live migrate VMs off that specific OVM Server to another OVM Server within the same server pool. It will then shutdown the Oracle VM server if no VMs are actively running. If OVM Server CPU threshold hold is once more exceeded, it will continue to migrate the VMs to other OVM Servers. If no other OVM Server is available , OVM Manager will then find an OVM Server that is shutdown within that OVM Server pool and start it up (assuming an OVM Server is shutdown and available within the server pool). Once started up, it will start migrating VMs off the busy OVM Server to load balance appropriately.
NOTE: One cannot set DRS & DPM, you must pick either or.
How do you set it up? Well it’s in the exact same location as where you would set DRS. Servers and VMs tab -> click Server Pools -> highlight <serverpool> -> click Server policy icon
