[rhos-list] EXTERNAL: Re: Instances showing up on the wrong host.

[Minton, Rich]

This has been resolved. I was able to us "virsh undefined" to get rid of the stale shutdown entries.

Thanks,
Rick

Not really enough info here to give a good answer. If you are still seeing the problem, can you show output from various 'nova' commands to clearly illustrate the problem. As a starting point something like these commands

 - nova list
 - nova show <instancename>
 - nova host-list
 - nova host-show <hostname>
 - nova hypervisor-list
 - nova hypervisor-show <hostname>

 - virsh -c qemu+ssh://root@<hostname>/system list

For "<hostname>" use the hostname visibee in the 'nova show'
output for the instance in question.

Nova ought to clean these up itself, but it must have had some problem in doing so. You remove them from libvirt's view by doing 'virsh undefine VMNAME'
