What about in production? Our servers use similar software to you (initially Xen 4.0.1, but now Xen 4.1.1 and a Linux 2.6.32-pvops kernel), but a few percent of our servers go down in a very nasty way every day. Dom0 becomes unresponsive, it feels it 'hung' and we have to force reboot the boxes. Do issues like this sound familiar? 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.htmlIn 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? Regards Andreas _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
