  • Thread-topic: VM does not start after shutdown

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 run_domain


  File "/usr/share/virt-manager/virtManager/domain.py", line 558, in startup

    if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self)
