Hi all,

Done a test install with a cluster and now running Ubuntu 8.04 on two
Dom0 nodes.
The problem I found was with the rc scripts at reboot, that heartbeat
didn't have time to perform live migration before the node rebooted.
Executing: reboot at the prompt I could see it started to prepare for
the live migration, but at the same time in the log I could see it
started to shutdown xend (not good if migration is not complete ;) )
plus other processes, so the migration failed.

They way I at least temporary solved it was to put a sleep command in
the heartbeat init.d script, in the scripts stop section. I put sleep
15 so it waits 15 seconds before moving along. Everything works now,
but it seems like a very cheap trick.

Anyone having a similar setup and experienced the same thing? All
software are from the Ubuntu repository.
I earlier ran Debian Etch and didn't have this problem.

Regards, Daniel
