Interesting....
you have a NFS share between several nodes ?
does the nova user have the rights to write on all the directories within /var/lib/nova/instances ?
May be a right issue...but not so sure

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,…..
