how can i enable and successfully test serial port passthrough to a windows 11 vm on pve? I've tried to do this without any success.

serial port passthrough

You want to pass through a physical serial port to the Windows VM?

That cannot be done through the web UI, but via the CLI:

qm set {vmid} --serialX /dev/ttyUSB0

This is just one example. Check which of the /dev/tty devices you want to pass through.

Greetings,

Thank you very much for your response. I ran the command qm set 102 --serial0 /dev/ttyUSB0 but now when I try to start the vm it wont start because of the error "Error: no such serial device".

You need to adjust the path to the actual serial device you have in your host
