I've already done this, there are some stack traces in the bugzilla

Andrew Jones seems to think that the problem in this case is actually in
the Xen hypervisor and not the guest. Problem is I seem to be the only

64bit multi-vcpu. The guest is quite heavyweight, 30GB of memory and
12vcpu. It's a LTSP server designed to handle lots of graphical logins
for computer science students.  This, I guess is not a common workload.
