Re: not able to start nova-compute "Instance could not be found"

Hi :-)
Did you use to have that instance and destroyed it - lost it while it is
still logged into the database ?
does $ nova list works, if so use it to retrieve the compute node used
for it and check /var/lib/nova/instances, or connect to the node, and
isue :
$ virsh list --all
