I have 5 "identical" VMs, created from a "golden_copy" of an
install of
Centos 5.5.
I have used :
xm shutdown -a -w
to shutdown all VMs, and wait for each of them to come down gracefully.
However, after restarting, one of the VM is not coming up anymore, with
a "device 0 not connected" error.
Traceback (most recent call last):
File "/usr/share/virt-manager/virtManager/engine.py", line 493, in

What is at issue? Any hints would be highly appreciated.
