Sunshine does not find Intel GPU hardware encoders in Win 10 VM though it is present and usable to other programs #2107

The same problem on iris plus 655, using GVT-g NEED HELP. |
|
Same here, GVT-g on I5-8500, UHD Graphics 630 in my case. Log shows identical errors ( |

Same here, HD Graphics 620 in my case. The hardware encoder works, however, in Parsec. |

Describe the Bug
When passing an Intel virtual GPU from Linux to Win 10 guest Sunshine does not find/use hardware quicksync encoders, though it is available and other apps like ffmpeg successfully detect and use it.
Because I am passing the gpu in GvT-g mode at first I thought maybe this just wasn't supported. However when I execute the following in the same VM, I get strong results:
ffmpeg -hwaccel auto -I demo.video -c:v h264_qsv -c:a copy h264.mp43-4x speedup, 10-15% CPU use
ffmpeg -I demo.video -c:v libx264 -c:a copy h264.mp41.5-1.75x speedup. 400+% CPU
Additionally monotoning from the Linux host, using
intel_gpu_topon the Linux Host, I can see Render/3D enginebeing in use, but crucially it also shows use of the Video Engine.
This never happens unless the decoders/encoders are being used and it does not happen when I run sunshine.
Expected Behavior
sunshine detects and uses the appropriate hardware supported H264 codec. ( or HEVC 8bit 4:2:0 which is also supported on Skylake )
Additional Context
VM HOST Information:
Mostly unrelated: it is also interesting to note that sunshine works fine on the Linux host with hardware encoding VAAPI and selecting H264
System is an Intel NUC 6i7KYK Skylake i7-6770HQ with integrated Iris Pro 580
