Re: [Openstack] strange problem when reboot nova-compute node: domain not found: no domain with matching name

Hey I just wanted to see if the domain was still declared within virsh database
in case you can also go to your instances directory and un a $ virsh define $instance-name/domain.xml
Can you post your nova.conf please ?

Hi Razique,
 
Is there anything need to have a deeper look?
Virsh list looks like well,same as the instance I created through nova boot.

Hello romi,

    Image got into a stuck state , only solution is to hack your database for this particular instance and mark it as deleted, den restart nova-* service, it would start working.

Hi,
 
I’ve installed essex and when I reboot one of the nova-compute node and next when I start nova-compute service again,the system promote:
Libvirt: QEMU error: Domain not found: no domain with matching name ‘instance-0000000a’
 
Then I found:  
#ls /var/lib/nova/instances
_base instance-0000000a instance-0000000b instance-0000000c
#ls /etc/libvirt/qemu
instance-0000000b.xml instance-0000000c.xml Network
 
So:
/var/lib/nova/instances/instance-0000000a# virsh define libvirt.xml
Domain instance-0000000a defined from libvirt.xml
And:
#ls /etc/libvirt/qemu
Instance-0000000a.xml instance-0000000b.xml instance-0000000c.xml network
 
Then I restart: nova-compute &, and nova-compute could normally started.
I did not understand why reboot compute node,and usually the first instance’s xml file was deleted and nova-compute will terminate.
 
By the way, when I create a new instance, the first line in the log also is : Libvirt: QEMU error: Domain not found: no domain with matching name ‘instance-0000000a’
 
Anyone who had met such a problem and why?
 
Regards,
 
romi
