Absolutely nothing.  4 guests (all pvops) are running.   It happens in
the night when load is very low.
I disabled C-states too from bios and I set max_cstate=1 as a kernel
boot option.  Still, no luck.
As I said this happened always in the night.  The only scheduled thing
running in the night is the 3ware Check S.M.A.R.T. Thresholds
self-test (it runs every day at 12.00 am.   Crashes happened at 01:06
am and 02:17 am.
Other info:  Xen dom0 dedicated memory and preventing dom0 memory
ballooning and more CPU time than the guests (credit scheduler).
So I really don't know how to reproduce it..but it happens :\
Thanks for your help
