That is configuring your dom0's networking. Guest network config is
done inside guest (which is what is happening with DHCP too, so
that's no different).

You have to arrange for the guest to configure it. In some Linux
distributions that is possible on kernel command line, e.g. in Red


…so at least the two instances of network details would be in the
same place. At least some of that works on Debian/Ubuntu as well.

Still, I'd rather do DHCP.
