Ok, I think I'm royally confused then LoL Please help me understand.Not sure why you say it won't work. As a matter of fact it works wonderfully well for both Windows and Linux VM. Intel GPU drivers recognize the SR-IOV iGPU and can take advantage of QuickSync transcoding.
If I install Plex LXC Installation, is this a brand new installation of a Plex install? How can this help a Plex server already running and installed on a Windows 11 VM?
