A tool to keep the host PC awake(inhibit sleep) while a VM is running.
It uses "libvirt" to track running VMs. To inhibit/uninhibit sleep, it uses the DBUS method "org. free desktop.PowerManagement.Inhibit.Inhibit"(destination "org.freedesktop.PowerManagement" and path "/org/freedesktop/PowerManagement/Inhibit").
I use xfce, and this method is provided by xfce-power-manager. To test if this method provided run dbus-send --session --print-reply --dest=org.freedesktop.PowerManagement /org/freedesktop/PowerManagement/Inhibit org.freedesktop.PowerManagement.Inhibit.Inhibit string:"YourAppName" string:"ReasonForInhibition"
Application exists and remove on all active sleep inhibitors on SIGKILL and SIGHUP. So, it can be safely autostarted on user login.
- Ensure libvirt is installed(see Dockerfile for dependencies)
- Optionally you can run
make test - Run
make build - Copy binary
libvirt-keepwaketo~/.local/bin/. - Copy
libvirt-keepawake.desktopfrom theinitfolder to~/.config/autostart/.This will make the application start when the user logs in.
Gentoo users can skip first and second steps and just use ebuild from init folder.
I have a desktop with a powerful GPU for ML, which is my main working/fun/projects PC. It has Gentoo(so no systemd) as OS. However, using the same GPU to play games on the PC, laptop, or TV downstairs is convenient. So, I use libvirt + qemu to run Windows 11 with GPU(and a few other PCI devices) passthrough. I use Sunshine installed on Windows 11 to stream games to different devices (For example, Moonlight on RPI5 connected to a TV). I want the host PC to stay awake while the Windows 11 VM is active.
