Yes, you are right. I thought I had selected a storage domain with
sufficient free space but probably it was not so.
I just repeated the operation, creating a snapshot and then a clone
the same VM and selecting an SD with sufficient free space, and it
completed correctly with the cloned VM able to boot.
I take the occasion to suggest oVirt to at least behave this way:
1) pre-calculate necessary space and in case of problems don't start
the clone operations but send a warning message impeding it
If during 1) all was ok and in the mean time went KO (unexpected new
storage allocated that made impossible clone completion)
2) notify the user with the actual problem (insufficient space) and
not those crypic messages....
see the already pointed link:
Those are indeed great improvement suggestions for a better user experience.
It will be great if you could add it in bugzilla (as RFE) so it can be followed and
