[Xen-users] Enable support for HVM and domU's Ethernet interface

Hello all,

I created my domU's Debian GNU/Linux Etch AMD64 using the debootstrap tool and I found out that it didn't installed a Linux kernel and modules. What I did was I copied the /lib/modules/2.6.18-5-xen-amd64 from my dom0 to /lib/modules/ of my domU. Was it right to do it that way?

Anyway, I have three (3) questions actually and here they are:

[1] How will I enable HVM support and make use of them on top of Xen?

[2] How will I enforce dom0's vif to use a single private IP address so that my domUs will use it as their default gateway?

[3] What Ethernet module shall I load on the domU side? I tried bringing up the eth0 interface from the domU side but it doesn't work.

Below are the things I did so far and some information about my current setup:
