That's what I tried (I skipped the patching), the VM didn't find any NIC when I added that option (maybe I did it wrong), like this:
net0: virtio=BC:24:11:D4:9D:A9,bridge=vmbr0,firewall=1,host_tunnel=off
@fiona was that meant for me ?
Edit: I guess so, I tried adding that option to the nic of the vm and turning checksumming but it then the network of the vm didnt work (no nic found in the vm)
Not the person you replied too but I tested and it didn't work with 10.2.1-2 but did with 10.1.2-7, I have a realtek nic though and my problem was internal dns didn't work in my k3s node.
