Comment 2 RHEL Program Management 2010-08-05 10:27:43 UTC

This issue has been proposed when we are only considering blocker
issues in the current Red Hat Enterprise Linux release.

** If you would still like this issue considered for the current
release, ask your support representative to file as a blocker on
your behalf. Otherwise ask that it be considered for the next
Red Hat Enterprise Linux release. **

Tried to reproduce it, for me it fails already during savevm. Migration to file seems to work fine.

Comment 8 Kevin Wolf 2011-12-07 11:14:06 UTC

Is this still reproducible? What happens if you try migration to file and then restart the VM from that file?

Doesn't look like the original problem is reproducible, and internal snapshots aren't supported anyway. Closing.
