Hey Joe, 
yes, several solutions there
First, check if the domain exists by running
$ virsh list --all (supposing you use libvirt)

check /var/lib/nova/instances/instance-0000002a
if the dir. exists $cd into it and run "virsh define libvirt.xml"
then restart nova-compute

If the dir. doesn't exist, you may want to update the nova database,  figure out your instance entry within the "instances" table and update the field "deleted" to 1

> Now, I've dumped all the DBs to disk and grepped through it for '00002a' and grep -R'ed /etc/ and /var/
> I can't find any reference to that anywhere, but it is causing nova-compute to fail to start.
> Anyone know how to fix that? If not, anyone know a cloud platform that isn't made from very thin glass, pre-shattered for your pleasure?
