Summary

This documents the use of SPICE to access a Proxmox VM Desktop from a “client.”

The VM (“guest”) OS is Debian 12.9, and I’m using a slightly older version of Debian 12 on the client laptop.

Steps

Follow the VM setup instructions at the above link (e.g., using SPICE as display type when configuring the VM), but two additional steps were required.

First, to even access a single display via SPICE:

• Install virt-viewer on the client machine (sudo apt-get install virt-viewer).

Second, to get multiple monitors (and automatic resolution updates based on window size!):

• Install spice-vdagent on the guest VM (sudo apt-get install spice-vdagent).

That should be it to get a SPICE session up and running for a Debian client and a Debian guest VM.
