Many times when we move or copy a guest we need to keep the same UUID. As an example we have a VM that is running Centos 4 that we need upgraded to Centos 6.2. How we have done this in the past: Build new VM Install fresh Centos 6.2 Copy over the application Shutdown the first VM Shutdown the 2nd VM and change UUID to match first Fire up 2nd VM if everything works kill delete 1st VM We run into all sorts of other situations when we make copies as backups and need to go to one of the backups. We never need to run a two VMs with the same UUID, but often have a box where we need to change the UUID to match what an old box was using.

[Users] Ovirt Engine as a VM
Had anyone created a how to or notes on how to manage an ovirt engine as a guest on the cluster? This should be possible, when the cluster is powered up for the first time it would require some specialized instructions to fire up the ovirt engine on a node. P.S. Are there any plans for redundant ovirt engines in the works?

Not sure I follow, VM name is good, but there are all sorts of things that care about UUID changing. That is why we are looking for the ability to set it. Today it looks like all UUIDs are random, and I assume that a UUID needs to be unique, but how hard would it be to be able to specify a UUID? Libvirt allows this to be done and we do it all the time in our XML kvm files.

Not sure I follow, VM name is good, but there are all sorts of things that care about UUID changing. off the top my head I can think of - permissions - events - tags - quota Permission and Quota can be handled manually the other two won't point to 'new' VM.

Libvirt allows this to be done and we do it all the time in our XML kvm files. Changing VM id does not sound like a complicated feature, when designing such a feature need to think of what are the impact on the history DB and events in the audit log (if such id was in use before).
