Im using a windows 10 VM for plex and wanted to add a GPU for trans coding.  I got the vbios file from tech power up, ensured there is no NVidia header and loaded it.

 

When I start the VM with the vnc graphics card everything works.  If I start it with my GTX 460 selected with the bios file, the machine hangs, not responding to pings or remote access and the last line of the log reads

-------

2021-03-12T13:41:33.877400Z qemu-system-x86_64: warning: guest updated active QH

-------

 

If I select vns as the first graphics card and the GTX 460 as the secondary, I can get the machine to boot, get into windows for about 30 seconds before it will lock up with the same error.

 

Im open to suggestions, Im tech literate, but not he best with VM's

I should add, HVM and IOMMU are enabled, and here is my XML file

Why not use a Plex docker instead?

In looking into this option I found that I am unable to use GPU pass though as Unraid does no include NVidia drivers. 

 

If that is not correct or outdated then that could be great.

The latest 6.9 release of Unraid makes it easy to install drivers for AMD, Intel and Nvidia GPUs. The AMD and Intel drivers are included and can be optionally enabled. Nvidia drivers, being proprietary, can be installed via a plugin.
