If you comment out those two lines and don't provide an alternative then the
network backend interface will not even be brought up. It's then no surprise
that no traffic can get to or from your HVM guest.

If you want to route traffic rather than bridging it then you need to add
commands to set up a route to your VM. And you almost certainly want to keep
the first line that you commented out. That's the one that actually brings
the interface online. If routing you'll want to put an actual IP address
rather than 0.0.0.0.

I don't think an IP address can currently be specified to that script, by
the way. At least not directly.
