Description geraud 2022-01-31 07:50:53 UTC 
We are using FreeBSD VMs under the Proxmox virtualization system, and qemu-guest-agent to interact with them from the hypervizor.

Last week I upgraded one of our 12.2-RELEASE VM to 12.3-RELEASE and noticed that the qemu-guest-agent didn't work as expected. Upon further verification, it looks like the virtio_console doesn't create a /dev/ttyV0.1 as it previously did.

Running `pciconf -lv` indeed doesn't report a 'Virtio console' device anymore.

I'll admit that I'm perfectly clueless on how to debug/fix this kind of issues, any pointers will be much appreciated.
