Hi, I've also recently hit this bug und it should be fixed by [1], also see the original analysis at [2].
Passing "allow_unsafe" as a Hypervisor option circumvents the crash. A serial boot log is attached. [1]: http://lists.xen.org/archives/html/xen-devel/2012-10/msg01856.html [2]: http://lists.xen.org/archives/html/xen-devel/2012-10/msg01396.html Regards, Christian
