Re: [Users] Ovirt 3.4rc + Qemu Live snapshot : Problem to delete a Snapshot
Hi Eric,
Live merge is not yet supported (IIRC by qemu). From the Live_Snapshots wiki page:
"Live merge is not present in the upstream component yet (libvirt/qemu)"

This is the expected behaviour.

As far as I understand, revert means to go back to the point that you took the snapshot,
while delete means to stay at the current point of time but deleting the option to go
back.
OK, so given the Snapshot Actions Matrix, it should be possible to
delete the snapshot via a "Live Merge" operation. So, why the delete
action is not available while the VM is running? How can I enable this
feature? Or maybe this feature is in the roadmap?
Thanks,
Regards,
Eric
