If you’ve already started your VM and you’re noticing there is no guest agent use the following steps to add this feature.

First login to your VM and install the guest agent:

sudo apt update
sudo apt install qemu-guest-agent

Next, shutdown your node completely and enable the QEMU Guest Agent under “Options”.

Once enabled, start your VM.

Check to see that the guest agent is running:

ls /dev/virtio-ports/

You should get an output like: org.qemu.guest_agent.0

Go back to Summary in Proxmox and you’ll be able to see your VM network info.
