TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 The file /etc/network/interfaces does currently not exist. It's just all a mess and I can't get it to work. And most of the time people suggest using sudo /etc/init.d/networking restart or similar using systemd but evertime I get the message that networking doesn't exist which I find peculiar because everyone else does have it. Most of the time DNS is not working, or the ip addresses are messed up (completely different subnet), or the os has the correct ip but can't ping any other devices (not 1.1.1.1 but also not 192.168.2.79 which is my static-ip-ed win10 computer) or /etc/network/interfaces is ignored (the file didn't exist yet). Then I turned to SO and tried these ( 1, 2) but all with no success.Įvertime there's something wrong. Then I tried this guide but again with no success. Then I tried this video but also with no success. I started with this video but with no success. So, as far as I understand, I need to setup a network bridge. They both need to be accessible from "the outside". The os needs to get the ip of 192.168.2.15 with dns set to 1.1.1.1 and the vm needs to get the ip of 192.168.2.16. I have one ethernet port on my server (on the motherboard) that I want to use for both my os and the vm. The VM (using KVM and virt-manager) is TrueNAS Core (FreeBSD). The host (os of the server) is Ubuntu 20.04.4 LTS. I'm having quite a lot of problems setting up a network bridge for both my host and my vm to use.
