create a bridge, eth0 does not exists

Hi all, I am trying to create a bridge for VMs. x
When I am trying to add eth0 to bridge, I got error:
$sudo /usr/sbin/brctl  addif br0 eth0
interface eth0 does not exist!
This is the result of ifconfig:
$ ifconfig





Now I am wondering how can I create eth0 or which interface should I add to bridge?

I assigned the p13p1 to the bridge and I lost my connection, now I cannot ssh at all to my server.

Bad move. Stuff like this implies network connection loss.

If you want to create a bridge for VMs, you have to transfer the physical device's network config to the bridge leaving the physical device with no IP address (at least i did it like this and works). Naturally you will have to change any routing/firewalling you have there to accomodate the new device name.
