I am currently in the process of creating a GPU passthrough system and I’m using lookingglass to view it. I have followed the installation guide and have been able to get it running with autostart, scream over LAN, etc.
After a few minutes (Anywhere from 5-30) the performance of the guest OS tanks. The mouse will skip around, programs will not open, the start menu takes over a minute to open, etc. In one case video just cut out entirely and I was left with a black screen, but I haven’t been able to reproduce that issue so it may have been a fluke. But if I boot the guest and immediately kill the looking-glass-host process with task manager, viewing the VM by plugging the GPU into a monitor, the guest will never deteriorate.
I am a Looking Glass and KVM noob so I am at a loss for ideas about how to fix it. I’m not sure if I’ve misconfigured something or if there is a problem with the application. I can provide any files needed and if you need more information I’ll do my best to give it.
Thank you in advance for any help.
