Ah, so you mean the libvirt QEMU driver isn't working. The best first step to diagnosing those problems is to stop the libvirtd daemon, and run it manually with debugging enabled LIBVIRT_DEBUG=1 /usr/sbin/libvirtd with any luck there will be some failure reported explaining why the QEMU driver didn't activate.
