[ovirt-users] Snapshot self-hosted engine?

[Derek Atkins]

Hi Martin,

Keep in mind this is a single host..  so..  is there a command line
operation I can run from the host to snapshot the running engine VM?  Then
if then update fails I can revert (by command line) the running VM from
before the update.  I don't mind getting my fingers dirty if I have to
script it.

I've used the "engine-backup" tool, but frankly IMHO a snapshot is a
better way to handle an immediate update, rather than having to completely
re-install the VM and restore from backup.  This operation is exactly why
snapshots exist.  :)

Thanks,

-derek
