Update existing templates and populate changes to already deployed VMs.
In one of our support cases about updating en deploying templates, the answer of RH support containted this section:
"There is an enhancement already filed to make it possible to modify an existing template and populate changes to already deployed vms. Future version of RHEV may include this feature."
With that a BUG# (unfortunatly not accessible to me): https://bugzilla.redhat.com/show_bug.cgi?id=558995
Does anybody have any information about this (any non-private source, maybe some work on oVirt?). I'm really curious how it would work to update templates/vms this way.
Thnx!

RHEV 3.1 will not include this feature. There are some partner solutions that might be able to provide this functionality, so keep an eye on marketplace.redhat.com
if you raise a case asking for the same thing, it will be attached to this BZ, making it weigh more than it used to with a case from a single customer. It's a bit like voting, without the extra democracy bits :)
Vincent,
For what it's worth--I think the use case mentioned above is a good case for Puppet. We lay down a very small template ("Golden image"), and then deploy Puppet on top of each host to handle our configuration management, additional packages and generic changes.
