Comment 1 Ralf Müller 2006-01-30 13:59:57 UTC

Additionally one DomU did not come up because it missed a logical volume. On reboot the system had a complete hang up - no information has been logged about this hang up.

Comment 2 Clyde Griffin 2006-02-23 00:09:00 UTC

Not going to go back and fix SL 10.0 issues.  Retry on SL 10.1.
