Happy Friday, everyone! With all the discussion about Oracle VM Templates on this blog in the last week or so (here, here, and here), I thought highlighting a short video that summarizes Oracle VM Templates and Oracle Virtual Assembly Builder would be interesting. Click below to watch (it's just under 4 minutes):

Happy Friday! Our tip this week is on a little quirk of using Oracle VM 3 with templates developed in Oracle VM 2.
Why do I see new Oracle VM 3 networks named xenbr0 and xenbr1 after importing an Oracle VM Template?
Answer by Gregory King, Principal Best Practices Consultant, Oracle VM Product Management:
Some legacy Oracle VM Templates as well as some newer templates are designed to come pre-configured with network interfaces for Oracle VM 2 environments. Oracle VM 3 doesn’t really know what to do with the pre-configured network devices during the import process of an Oracle VM Template, so the product errors on the side of caution by creating place holders for networks.
This means Oracle VM 3 automatically creates superfluous or false networks using the name of xenbr0, xenbr1, etc. when you import an Oracle VM Template that uses the Oracle VM 2 naming convention for bridges. So you are left with new networks named xenbr0 or xenbr1 that are useless since they are not associated with any servers, network ports or bonds. This can be quite confusing.
The problem is very easy to fix. Simply edit the newly imported Oracle VM Template, replace the networks named xenbr0 and xenbr1 with your real networks, then switch to the Network tab, highlight the networks named xenbr0 and xenbr1 and then delete them.
Here is a step-by-step example...
The next screen shot shows the superfluous networks after the new template has been imported:
The networks named xenbr0 and xenbr1 can safely be removed after they are no longer being used by the newly imported Oracle VM Template. Simply switch to the Repositories tab, find and edit the newly imported template as show in the screenshot below:
Finally, switch to the Networking tab, highlight and then delete the networks named xenbr0 and xenbr1 as shown in the screenshot below:
...and now your Oracle VM networks should look just like they did before importing the template :-)
We'll see you all next week with another tip!

We are pleased to announce the availability of Oracle VM Template Builder, an open source, graphical utility that makes it easy to use Oracle Enterprise Linux "Just enough OS" (JeOS) - based scripts for developing pre-packaged virtual machines for Oracle VM. Now, end-users and ISVs have the option to develop their Oracle VM Templates by using these JeOS-based scripts directly or via the graphical Oracle VM Template Builder.
Oracle VM Template Builder uses "JeOS" to facilitate building an operating system instance with only the absolute minimum packages needed for an Oracle VM Template, helping to reduce the disk footprint by up to 2GB or more per guest virtual machine, and to improve security and reliability. Oracle VM Template Builder is distributed as software packages via the Oracle Unbreakable Linux Network (ULN) and Oracle's public yum repository
See related press releases on Oracle VM Templates:
