Hello, I have just installed Xen and configured a virtual machine for the first time. I followed the following How To: http://www.howtoforge.com/ubuntu-8.04-server-install-xen-from-ubuntu-repositories When I did the initial install and configuration of the VM, the physical machine only had one NIC installed. I now want to install a second physical NIC in the machine and eventually have the VM utilize the second NIC. After installing the NIC, I logged onto the Dom0 machine. I then modified /etc/network/interfaces. After issuing the ifconfig command, I failed to see the second interface. My guess is that my approach is wrong since the Dom0 is really a VM as well. So how do I go about adding the second NIC and configuring the existing VM's to use it?
