53 * translates network connections to these magic addresses into
54 * userspace calls on the host (eg. connect(2)). qemu-doc has a nice

57 * NETWORK: The network.
59 * ROUTER: The address of the "host", ie. this library.
61 * [Note: If you change NETWORK and ROUTER then you also have to
62 * change the network configuration in appliance/init].

65 * magically connects this pseudo-address to the guestfwd channel. In
66 * typical Linux configurations of libguestfs, guestfwd is not
