That error is from libvirt, not qemu, so you are asking on the wrong
list.  But when asking on the libvirt list, be sure to mention what
version of libvirtd is running on nova-compute-lnx001.  Meanwhile, when
libvirtd gets in a stuck lock state, you can often restart libvirtd to
get past that point, with no negative consequences to your running qemu
guests.
