Hi all

I tried to run bonnie++ disk stresser in dom-U, who's disk is backed with non-local (on nfs) loop-back file.

The machine rebooted pretty quickly.

So, how do I tell what's barfing? Is it Xen? Is it dom-0 (nfs or loop-back)?

I looked in dom-0's /var/log/messages and didn't see any obvious record of a dom-0 whoopsie (but is that the right place to look etc...).

Any help greatfully received.

Incidently, I ran bonnie++ successfully in dom-U with disk backed by local (dom-0 ext3) loop-back file. This pleasantly surprised me, as loop-back files don't have a good rep for stability under load.
