Enable QEMU Guest Agent on Proxmox VE

After installing the package, enable it on the Proxmox VE Web interface (GUI). This is done under VM > Options section. You can see it’s disabled in our instance. Double click to open the dialog used to enable the feature.

Tick the checkbox to enable QEMU Agent for your VM.

QEMU Guest Agent will be enabled but a manual instance stop and start procedure is required.

Stop and Start VM Instance

Choose the instance and click on the dropdown list under “Shutdown”.

Confirm you want the Virtual Machine stopped.

Wait for it to go down then use the “Start” button to bring the instance up.

Once it’s live, you’ll see “QEMU Guest Agent” is fully “Enabled”.

Virtual Machine details such as IP address will appear on the Proxmox VE web interface.
