Hi,
I always met a FV-VM(redhat-5.4) hangs after about 48 or more hours
run on xen4.0.0 + Pvops dom0 kernels 2.6.32, besides, some workload also run
on dom0. Unfortunately I can only connect the VM with vnc and no reponse
with console. From “vcpu-list” found that there are two vcpu with that VM
but one have no state. After rebooting the Vm, I got the message in Guest
OS like:

Someone could give some hint what cause vm hang or how to get more
information? Thanks in advance!
