Hello,

I am setting up a Ubuntu server VM and getting the following error on launch

Code:
Error: Unknown device type.
can't create interface fwln101i0 - command '/sbin/ip link add name fwln101i0 mtu 1500 type veth peer name fwpr101p0 mtu 1500' failed: exit code 2

kvm: -netdev type=tap,id=net0,ifname=tap101i0,script=/var/lib/qemu-server/pve-bridge,downscript=/var/lib/qemu-server/pve-bridgedown,vhost=on: network script /var/lib/qemu-server/pve-bridge failed with status 512
TASK ERROR: start failed: QEMU exited with code 1

Is there something I need to add to /etc/network/interfaces? Where is the mistake? Can you please help?

/etc/network/interfaces below
Code:
auto lo
iface lo inet loopback

iface eno1 inet manual

auto vmbr0
iface vmbr0 inet static
address 192.168.1.2/24
broadcast 192.168.1.255
gateway 192.168.1.1
netmask 255.255.255.0
bridge-ports eno1
bridge-stp off
bridge-fd 0

iface eno2 inet manual

iface eno3 inet manual

iface eno4 inet manual


dmesg output is attached. (I am providing because a similar post asked for the same output):

What is the VM config? On the CLI: qm config <vmid>

Thanks for the reply

here is the output from the CLI
