Hi Rich,
I'm checking this option, as i didn't find PATCH2/2 for this thread, i'm
wondering how can i check the network
address of the appliance? i just found the following in libvirt xml file,
ue="/var/tmp"/>\n <qemu:arg value="-netdev"/>\n
<qemu:arg value="user,id=usernet,net=169.254.0.0/16"/>\n <qemu:arg
value="-device"/>\n <qemu:arg value="virtio-net-pci,netdev=
What the --network option does is it sets up a user network. This is
implemented in qemu in userspace (using a thing called SLiRP) and it
doesn't give the appliance a separate network address.

Also it has some limitations:

Nevertheless from guestfish you can test the network using debug
commands. For example:
$ guestfish --network -a /dev/null
