>> Hello,

>> What do you do when this crash happens? How to reproduce it?
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
