Hi everybody. We are trying to transfer our project from using
VMware
vCenter to oVirt. Everything looks good, but when it comes to snapshots
there is a quite big difference. In current application we are using VM
snapshots to switch the VM from one state to another.
Each VM has it's initial snapshot (we can go back anytime we need), but it
can also have several additional snapshots with some VM modifications (like
applications added or so). We are able to go from one state to another
using "revert to snapshot" function served by vCenter.
What I understand this is not possible in oVirt. If I revert from newer
snapshot to older one all snapshots that were created after the older one
will get deleted. I understand the reason (having one base file and having
only diffs per each snapshot) and here comes the question...
What would be the best solution to simulate this vCenter option? To be
able to quickly swap from one state to another (and back of course) on one
particular VM?
Perhaps "Preview"? Then you can boot the VM, do stuff, shutdown, and
"Undo".
Or, for slightly more complex cases, you can create/clone a VM from a
snapshot.
For even more complex ones, you probably want to have a look at templates.
Best regards,
