That doesn't make any sense. The waiting code here is about the QEMU
process' initial startup sequence - ie the gap between exec'ing the
QEMU binary, and it listening on the monitor socket.  PXE / nfsroot
doesn't get involved there at all. Even if it were involve, if you're
seeing 5 minute delays with only 8 vms on the host, something is
seriously screwed with your host. This isn't a compelling reason to
add this config option to libvirt.
