Do you get any errors in the dom0 kernel dmesg? Or in Xen hypervisor
dmesg/logs?
All the drivers load correctly?
Try these commands:
dmesg
xm dmesg
xm log
Also add "loglvl=all guest_loglvl=all" parameters for xen-3.4.1.gz.
You might also want to add "dom0_mem=2G" for xen-3.4.1.gz.
Or something that is less than 4G.. just in case there's some 32bit
counter/variable bug.
