I have a Windows 10 Pro v1903 VM running on my Unraid v6.7.2 server. - Passthrough was previously working headless w/ a DisplayPort dongle (remotely accessible via RDP or TeamViewer). However, when I attempted to run it like a traditional workstation (w/ a known working monitor, keyboard and mouse), I lost the ability to pass the GPU-through (resulting in BSOD boot-loops).
The system itself is running on a single EVGA GTX 1660 TI board. - No other GPU's are present, and integrated graphics is not an option w/ my CPU.
I have previously went through the process of exporting my vBIOS using GPU-Z and modifying it w/ a hex editor. - Passing either the modified version or the original file no longer helps.
Running DDU (and disabling auto-driver download) resolves the bootloop issue, but is only accessible via remote methods (mentioned above). - My monitor will remain black/blank. - Cannot successfully reinstall drivers.
As for the VM error log, I am seeing the following:
2019-07-27T19:34:57.873893Z qemu-system-x86_64: vfio_region_write(0000:27:00.0:region1+0x1210c8, 0x0,8) failed: Device or resource busy
