You may have a look. > http://bugzilla.xen.org/bugzilla/show_bug.cgi?id=1730 OK, first of I am really excited that you guys are using the upstream kernel and testing against the latest. I think the issue I've seen before and it was due to a mix of vCPU hotplug code. If I booted the kernel with max_cpus=16 (on the Linux command line) and did those operations it worked. But it is a bug nonethless.
