I eventually just set up a script that looks for active qemu/kvm instances every 15 minutes. I set up the guests to hibernate, because for some reason the… ‘double sleeping’ of the guest and host seem to put the GPUs in a weird state when it wakes. After this, I just have a systemd hook for suspend/resume that fires the instances back up when the host wakes.
It actually works pretty flawlessly in the end. I probably sleep/unsleep the thing a few times a day with no lockups or issues at all, I just have to make sure i never manually suspend it.
