[ovirt-users] Error: Storage format V3 is not supported

[Vered Volansky]

I've reported the issue:
https://bugzilla.redhat.com/show_bug.cgi?id=1323462

A verified workaround is to change the metadata Version to 0.

Checksum should be compromised by it, so follow
http://lists.ovirt.org/pipermail/users/2012-April/007149.html if you have
any issues with adjusting it.

Please let me know how this worked out for you.

Regards,
Vered
