[Xen-users] How to Configure Xen for Networking, System Use Case - NetVM
While the typical intent to have a vm for network interfaces is to
isolate dom0 the network, my additional intent is to isolate dom0
from my tinkering with the network. I have broken my dom0 beyond my
repair many times.
I would like to determine how to build a VM for the network
interfaces. And how to establish networking to other VMs.
Additionally, are there any reasons to bring a network to dom0 now
that it has been purposefully isolated from the outside (other than
the mouse and keyboard).
What I have been having the biggest challenge with is that bridging
cannot be used with wireless.
[Wireless base stations generally only allow packets with the source
MAC address of NIC that completed the initial handshake. Therefore,
without MAC rewriting, only a single device can communicate over a
single wireless link.]
The next solution I have tried is etables, which I have been unable
to get working.

My challenge here may be that I did not get the right configuration
process. I found bits of what the configuration should include but
I did not find a step by step method.
I was wondering about using libvirt but looking into it, I see it
requires building a bridge with bridge-utilities which seems in
conflict with my need for a wireless front end. Maybe the libvirt
iptables provides a solution around the conflict but I don't see
it.
The openvswitch seems to invoke a similar method as libvirt.
What should I be looking at to find an appropriate solution?
