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/>
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,
Ive 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
instances 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
