FYI, we think we've got the problem fixed & have a new build available.
If anyone is running rawhide with Xen and seeing crashes/hangs/wierd
behaviour, please give the 2.6.20-2925.8.fc7 kernel a try. Its not in 
rawhide YUM repos yet, but you can it from Koji

http://koji.fedoraproject.org/packages/kernel-xen-2.6/2.6.20/2925.8.fc7/


NB. this requires xen-3.1.0-0.rc7.1.fc7  userspace.
