This is implemented in qemu in userspace (using a thing called SLiRP) and it doesn't give the appliance a separate network address. https://en.wikipedia.org/wiki/Slirp Also it has some limitations: http://libguestfs.org/virt-rescue.1.html#network Nevertheless from guestfish you can test the network using debug commands. For example: $ guestfish --network -a /dev/null Welcome to guestfish, the libguestfs filesystem interactive shell for editing virtual machine filesystems.
