IMHO there's too much forking going on here. With the stateful driver we 
should have the daemon be the parent of the forked VM as per the QEMU 
driver. This will avoid the need to unsafely re-write the config files. 
It will also enable errors during the domain creation process to be correctly
propagated back to the caller.

eg, when I tested this patch 'mount' failed, but the libvirt driver still
thought all we fine becasue this part of  domain creation was being done
in the double-fork()d child and thus no errors could be propagated back.
