A customer sent me an industrial server for testing, pretty interesting stuff for trains, planes and boats. I have added a new PCIe NIC to my workstation and I wanted to put it inside my libvirt NAT network which I use for testing Foreman and Satellite.
Surpringlisly it was not easy to figure out this for me, luckily Patrick Talbert of Red Hat helped me to find a command that does exactly what I wanted:
# nmcli con add type ethernet ifname eth1 slave-type bridge master virbr0
eth1 is the physical interface and
virbr0 is libvirt NAT
network bridge (named default). For different networks find the proper network
with the following command:
# virsh domiflist <guest>
And with the ‘source’ network name, find the actual bridge name:
# virsh net-info <network>
Thanks to Patrick for helping me with this!
