[Users] oVirt 3.2: impossiible to delete a snapshot?

Wednesday, 27 February 2013

oVirt 3.2 with node f18 and engine another f18 and ovirt stable repo.

After I create a snapshot of a powered off win xp VM, I then select
the snapshot and select "delete"

Are you sure you want to delete snapshot from Wed Feb 27 07:56:23
GMT+100 2013 with description 'test'?

ok

Error:

winxp:

    Cannot remove Snapshot. Removing the VM active Snapshot is not allowed.

Is this expected? Why?

Thanks,
Gianluca
