Hey Romi,
looks like the image is not totally spawned, meaning it doesn't get added to Virsh, during the spawing, look at the /var/log/nova/nova-compute.log and look for errors.
Can you send the file ?

Razique,
 
Additional information:
Another testing system was not full of testing job. I met this problem before at my small system. If I use ubuntu image download from network,this problem was not happened. If I use centos and windows image create instance,this problem will happened,and in the process of building centos or windows instance, nova-compute always promote: libvirt qemu error,domain not found. But finally instance would run normally, and then to reboot the host of nova-compute and then run nova-compute ,it would stop at :CRITICAL error: libvirt qemu error, domain not found,…..

Razique,
 
Appreciate for your attention.
 
# ls /etc/libvirt/qemu/networks/autostart
default.xml
 
at my memory,when the first time I computed the system installation, reboot  compute-node have no problem, and then after I created centos and windows instances (in the booting process,system show :libvirt qemu error: domain not found) and reboot one of compute-nodes ,nova-compute stopped and show me : CRITICAL error, Libvirt: QEMU error: Domain not found: no domain with matching name ‘instance-0000000a’. then the others also have same problem.
 
At my corner,it is a sysmatic behavior.
 
But at my another testing system, this problem had not happened.
 
Regards,
 
Romi

Hey, 
could you remove the flag :
--resume_guests_state_on_host_boot=true
ans restart the nova-compute service 
 
Can you run
$ ls  /etc/libvirt/qemu/autostart 
 
Does that behaviour is systematic ? Everytime you restart the service nova-compute, or do you need to also have your compute node restarted ?

Razique,
 
Thank you very much!
 
Here is the paste:
http://paste.openstack.org/show/20938/
 
this config was fine at the first testing system.
 
Current problem occurred at my second testing system, and at before I created raw format image and convert to qcow2.
 
I am going to recreate image directly on qcow2 format,are just in processing,……
 
Is there anything should be cared with image? It looks like related with the glance image,I guess.

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
