Re: [Openstack] nova-compute not starting

Thu, 13 Dec 2012 02:56:28 -0800

I think the instance ID is the database ID (base 8) encoded in base 16.  0x2A = ID 52 into the database.
Did you updated the ID 52 ?

I may be wrong ^^

It turned out to be that last one. What I don't understand is where openstack found the instance id from. That doesn't exist in the database, or anywhere on the file system I could find.

Kind regards

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

Hi guys,

You think you have Openstack working, then you cough and it all breaks.

I'm getting the following error when trying to start nova-compute after a reboot of the compute node (to install non-related patches)

libvirtError: Domain not found: no domain with matching name 'instance-0000002a'

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?
