[Xen-users] Xen reboots on dom-U disk stress...

[Roland Paterson-Jones <roland@xxxxxxxxxxxx>]

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.
Regards
Roland
