Patrick, can we get:

* virsh dumpxml (while running) (I think we had this from fence_xvmd; I'll look
at IRC logs)

* original domain config

[REBOOT] Calling virDomainDestroy

Feeding in the *unaltered* XML to virDomainCreateLinux(), we get:

libvir: Xen Daemon error : POST operation failed: (xend.err 'Error creating
domain: int argument required')

If possible, libvirt + xen RPM versions might be helpful, I think, too.

[root@bid-04 xen]# rpm -q xen libvirt
xen-3.0.3-25.el5
libvirt-0.1.8-15.el5

Ok, we need to flip the port to '-1' for the graphics block.

Also, for full-virt instances, we need to *not* kill the <os> block.

Allows hvm rebooting

I regression-tested this on a 5-node rhel5 cluster w/ paravirt rhel5 guests as
well as a single-node full-virt setup.

Works for me :-)
