VM Boot issues with VNC

[TheSnotRocket]

So, this might be backwards from what you normally see - and it's a problem.

 

I have a Win10 VM that refuses to boot (most of the time) with VNC as the video card.

If I pass through my NVIDIA card, it will boot.

 

I'm on 6.9.1 and this wasn't an issue with 6.8.

 

I don't want to use the nvidia card for the VM as I use the card for Plex and Emby - any thoughts on why VNC breaks my VM?

 

Start the VM, pop open VNC - bios loads, Win10 start circle spins maybe 1-2-3 times and then locks.  Only way back is to force a power off.

 

This is my working, with the NVIDIA card log:
