How did you accomplish this? Could you be specific on how this occured?
What version of Xen are you using (I presume xen-unstable + 2.6-pvops
(xen-tip/master))?
We were running our video conference server on a DomU after about 15 video
calls it crashed, it's very repeatable.
Dom0 is Centos 5.2 linux 2.6.18-128.2.1.el5xen xen 3.4.0 from
http://www.gitco.de/repo/xen3.4.0
DomU is Stock Fedora 11
