I created some snapshots, a long time ago, using the xml description option, so the snapshots have a name with a space in it...

Really a bad choice apparently, since it seems impossible to delete them now: I cannot find how to enter the snapshot name properly due to the space.  Quotes don't seem to help; escaping the space doesn't help either.

Anybody knows how to solve this?

eg:
snapshot-delete DOMINO1-prealloc --snapshotname 'W2K3-virgin install'
error: Domain snapshot not found: no snapshot with matching name ''W2K3-virgin'
(-> notive also the extra ' added )

root@VLET3:~# time virsh snapshot-delete DOMINO1-prealloc "W2K3-virgin\ install"
error: unexpected data 'install'

Thanks, Juergen
