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, ..

At my corner,it is a sysmatic behavior. But at my another testing system, this problem had not happened.

Everytime you restart the service nova-compute, or do you need to also have your compute node restarted ?

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.

Virsh list looks like well,same as the instance I created through nova boot.

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?
