Bug#534880: Same problem here

[Ludovic Gasc <lg@dmoon.be>]

Hi Everybody,

I confirm this bug on three different servers, with amd64 architecture.
I've updated all dom0 and domU with linux-image-2.6.26-2-xen-amd64 2.6.26-20 and reboot the servers at 2009-12-20.

Since this upgrade, we already have two domU in unresponsive state, with the same behaviour in this bug report (ssh, ping, xm console, etc...)

Each time I've added a domU with vcpu > 1 on a physical server, the time between each unresponsive state is reduced.

I've posted a bug report on the Xen's bugzilla: http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1564

We don't have Xen development skills, but we can recompile our kernels with some options to generate a backtrace.

Yours.
