Hmm, I guess I'm missing how this happens? If you do a --without-qemu,
the qemu code is never registered.

#ifdef WITH_QEMU
    if (qemudRegister() == -1) return -1;
#endif

It seems to be the only code which registers this code??
   virRegisterNetworkDriver(&qemuNetworkDriver);

Ah, good to know.. I have the base 0.3.2 code working now.  I need
to start looking at the remote functionality now. I should have some
patches posted in the next couple of days..
