Adding Timothy to the thread. Remove live snapshot is not supported yet, but it's in the roadmap. For now VM must be shut down before removing a snapshot. On 03/19/2013 07:11 PM, Gianluca Cecchi wrote:

I can create a snapshot, but how can I revert it. Need to has the VM off?
I confirm that also in my oVirt 3.2.1 when the VM is running the "delete" is greyed out. I successfully tested that if I shutdown it, then I can complete snapshot deletion. during deletion

I don't know how oVirt 3.2.1 is positioned vs rhev 3.1 but I found this:
- rhevm 3.1 manual is wrong in my opinion at page 139 section 8.9.3 because in create VM from snapshot it says: Ensure the status is Powered Down. and I think this is not true (possibly cut-n-paste from procedure 8.20 to 8.21 and forgetting to leave off the power down thing...)
- rhevm 3.1 at page 141 section 8.9.4 procedure 8.22 is not clear because it doesn't say if the VM has to be powered down for the snapshot to be deleted or can be running.... any information for both RHEVM 3.1 and oVirt 3.2.1 and snapshot deletion? Thanks for pointing that out, Timothy, perhaps you know who can help with that issue?
