Serge and Leo, We are using hardware RAID, no multipath.
We did not preserve any of host or VM syslog or bootlog entries from that time. The messages.log shows a kernel restart at 12:31:16 on VM01. We also have the postgres logs and they show a restart 2011-04-05 12:31:23 ... database system was interrupted; last known at 2011-04-05 12:22:24 ... incomplete... database system was not properly shut down; automatic recovery in progress ... the database system is starting up ... unexpected blah, blah ...starting up and all was well after that. VM02 also has a postgres log and it shows a restart at 12:32:13 which is probably when I manually restarted the VM. I'm pretty sure that both VM's got shut down. I watched them disappear from the desktop tray (lower right) and when I got the gui VM manager back up on the host, they were NOT running. >From the host Gnome gui, I run a couple of bash shells, a master system monitor (so I can see ALL of the cpu's) and then I launch the gui VM manager, launch a console for each VM, toss them into desktops 3/4 of the host and then start 'em.
