I want to use a hardware nic in a domu machine and preferably not go through a bridge, right now i have three nics and tree bridges set up with xen. they all use their own peth.

I am having troubles with a router that is run as a domu and it would be nice if the domu ciuld accesss the nic directly without having to go through a xen bridge.

So, if it is possible, how can i male a domu use a hardware nic without going through a xen bridge?

I think you should try PCI passthrough. A good post about this:

An alternative to bridging that doesn't involve PCI passthrough is routing:

That way the NIC can remain unbridged on the dom0. You just route and optionally NAT all traffic from the virtual interface to the outside network, and back of course.
