Comment 1 Oved Ourfali 2012-06-28 11:49:48 UTC

I tried to reproduce it on latest upstream, and preview succeeded for both snapshots.
Also, tried to use floating disks as well, and it succeeded as well.
(Did the test as you said, on nfs storage domain).

This bug is on downstream, not upstream, therefore I recommend testing with downstream build.
