Re: [vfio-users] Preventing host from going into sleep

As it turns out, it's not just about permissions; doing anything too complex in the wrapper script can interfere with the way libvirt manages qemu VMs and make it unable to shut them down properly (whether that's due to signal propagation in bash scripts or arguments being altered in some way).

Re: [vfio-users] Preventing host from going into sleep

The thing is that I want my computer to be able to go to sleep at the press of a button *unless* I'm running a VM. Systemd-inhibit does exactly what a want here, complete with a warning and an override prompt, but I haven't managed to get it to communicate properly with the system dbus when it'

Re: [vfio-users] Preventing host from going into sleep

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

[vfio-users] Preventing host from going into sleep

I've had my fair share of lockups because I forgot to turn off my VM before putting my host to sleep, and I've started looking into some sort of lock to prevent that kind of mistake. Normally, I'd use something like `systemd-inhibit
