Not in this year of my stability tests. In this year I am always
experiencing crashes of domU only. dom0 was always stable.
But last year, I hunted a very serious problem which causes nasty
hangs/crashes in dom0 (which crashes domU as a consequence). See this
mailing list post:
http://lists.xen.org/archives/html/xen-devel/2010-09/msg00556.html
In my tests it clearly shows that if you have a CPU without ARAT and you
don't have the patch from my post, your Xen 4.0.1 or 4.1.1 will crash
under load and/or after a while. What is your CPU?
