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):

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