Having a hard time getting a guest VM to join the local network. Config is Debian 10.4 with all the required KVM packages and I can create a VM (also running Debian) and access it through VNC just fine.
However, I cannot get the network bridge to function. It is connected to the 2nd NIC on the host (which is set to 'manual') and the status of the host NIC stays 'UNKNOWN' as well as the guest NIC (vnet0). What am I missing here?
Content of '/etc/network/interfaces':
Code:
auto lo
iface lo inet loopback
