Rather suddenly my Nvidia GPU no longer passes through to my VM's.  About two weeks ago I changed my cache drive from SATA to NVME and my VM's still booted and played just fine.  Then my windows VM would not output to my monitor, but my Ubuntu VM would, so I continued to use that one.  Now neither output to the monitor and I'm not sure what happened.

 

I never keep precious data in my VM's so I've deleted and started new ones, which didn't fix it.  I've changed the bios the GPU was booting with and checked the Nvidia .rom file.  I just haven't been able to figure it out with the free time I've had.  The VM's work fine as VNC so I've used them in that way for some of what I need but I'd love the display back for movies and gaming.

 

Does anyone have some advice to point me in the right direction?  It would be greatly appreciated.

Just a minute ago it worked for my Ubuntu VM again until I shut it down.  Then I tried my Windows VM and nothing at all.  Went back to Ubuntu and now it won't output.

Taken from the Ubuntu VM log after starting it and waiting.
