Setting Up a DHCP Bridge in Ubuntu 10.10 for Virtualization
Setting up a network bridge allows you to give a virtual machine it’s own IP address and make it accessible from the outside. A DHCP bridge is useful in a smaller network where static IPs aren’t assigned - like in a home or small office. You’ll want to do this if you’re setting up LXC or KVM.
This is what my /etc/network/interfaces config looks like.
`` auto lo iface lo inet loopback
auto eth0 iface eth0 inet manual
auto br0 iface br0 inet dhcp bridge_ports eth0 bridge_stp off bridge_fd 0 bridge_maxwait 0
The 2nd block configures your hard connection - in my case it's eth0. The last block configures the virtual device - br0, to bridge using the eth0 connection. If yours is named differently, you'll want to change the settings appropriately. Last step - restart networking.

I'll be setting up KVM in a future tutorial. Have fun!
