When I reboot my vm today(reboot works well before), it show :

*2012-01-20 16:55:19,112 WARNING nova.virt.libvirt_conn [-] Error from

why it happened ?

Then I goto the instances dir, add
<uuid>60f24c80-aee7-8e21-a14f-0682b82b13e2<</uuid> to ***.xml
use "virsh create ***.xml" to create an vm, then I reboot again , it failed.

Otherwise , I use "virsh define ***.xml", then I reboot again, it
successfully.

I want to know is it  correct ?
