[SOLVED] Complete beginner question - second VM won't start up

[positive11]

Hello,

Yesterday I decided to try out Proxmox on Intel NUC NUC6i5.
After installation I deploy single VM running Home Assistant (following this guide - https://community.home-assistant.io/t/installing-home-assistant-os-using-proxmox-7/201835)

Now I want to deploy second VM running Ubuntu Desktop. After I create the VM and press start button, the error bellow appear.

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

stopping swtpm instance (pid ) due to QEMU startup error
TASK ERROR: start failed: QEMU exited with code 1

Till now I notice that if I remove the NIC from the second VM it can start, but I don't know what I'm doing wrong. i'm using default settings, both VMs are connected to "vmbr0"

This sounds like you have some mismatched packages installed.

Did you install the latest updates?

What is the output if you run apt update?

It seams I forget to reboot the server after I run update it, Single reboot of the host fix the issue.

Good to hear.

I went ahead and marked the thread as solved. You could do so yourself as well by editing the first post and selecting the prefix in the drop-down menu next to the title.
