I have about 20+ Ubuntu Guests running on Vmware Server 2.0.2 and every night a backup script takes a snapshot of all running VMs, backs them up, then removes the snapshots.
Every morning I check the machines to find at least 1 or 2 are somehow corrupted. It can happen in guests running Ubuntu Desktop and Ubuntu Servers in versions 8.04 through 9.04. Here is what I mean by corrupted:
1) Postfix dies
2) Zarafa server dies
3) cron jobs on web servers die
4) Firefox dies
5) Gnome Desktop dies
If I reboot them then everything goes back to normal. However, it's causing a LOT of disruption. Are snapshots just flaky? I hate to shudown all the VMs in order to do a nighly backup, but I will if I have to.
