I'm trying to get virgl running on a Debian 12 guest, for Jellyfin, but even though I have virgl enabled, and the card shows under /dev/dri, I don't know how to check that it's being properly used. I'm getting weird errors

The error says kernel 4.16 or newer is required. I am, of course, running kernel 6.1.0, and I'm not sure how to troubleshoot.
I have libgl1 and libegl1 installed on PVE. Wasn't able to find any other documentation on what to do in the guest, if anything.

Any ideas?
