I am having an issue setting up a bridge for my KVM guests. I have set up the bridge, br0, in /etc/network/interfaces and linked it to my network interface, eno1. When I bring it up using brctl, it shares the ip with eno1. However, when I bring it up, the host loses network connectivity. I can't get out to the Internet with the host machine nor can I ssh into it locally.
Because the server has two network cards, I used a switch and attached both to the router. Running ifconfig, the bridge is still sharing 192.168.1.16 with eno1, and eno2 now has it's own ip 192.168.1.17. However, the host still can't get out and I can't ssh in.
Looking at my router's configuration, there is no device leasing 192.168.1.16, and 192.168.1.17 is now listed as the bridge connection (it was 192.168.1.16 before connecting the second NIC to the router).
How can I keep the host's network connection when bringing up the bridge, or how can I re-establish it after I bring it up? I've done a lot of searching but can't seem to figure it out.
