Not at this moment, and this is not planned for the future, afaik.

Did you play with the other SDK examples etc suggested during this thread?

May I suggest that this is best done as a plugin/contribution to a backup
solution, not standalone. I guess most sites with more than a few hosts use
some such solution - FOSS (amanda/bacula/backuppc/etc) or proprietary
(netbackup/backupexec/acronis/etc) - and backup of VMs (ovirt or other)
should be handled in this scope.

Searching the net I manage to find [1] and [2], which might be what
you want. Note that I never tried any of them myself.

Best,
