very good. I see that they care so much about this topic.
Hi,
I came here because I have the exact same problem. DDA works Well for me. Nested Virtualization also works well. As soon I enable both on the same VM at the same time either the GPU will not work, or the machine blue screen and is stuck in a reboot loop.
I am using:
Did anything actually confirmed if it's supposed to work or not ?
Thanks in advance
which kind of motherboard do u have ?
Hi,
We are using a Dell Server (Poweredge R720)

so,you have more chances than me to make it work,because I tried with a consumer mb,like the aorus pro and a consumer cpu (I9-9900k).
and I have also the nvidia RTX 2080 ti. so I have 0 chances :D
On My side, I can confirm it Doesn’t work, but this is an old Enterprise Grade GPU (4 GPU on a card) that is no more supported by Nvidia so I thought it could be a problem with the driver or something…
This is why I am wondering if it’s supposed to work or not.
I may end up opening a paid support case with Microsoft to know. If I end up there, I’ll post result to let you know

Can the Nested Virtualization Extensions and Discrete Device Assignment (DDA) for VGA Passthrough concurrently enabled for one Hyper-V Generation-2 VM in Windows Server 2016 for a Windows 10 Guest VM?
Every time I try to enable nested virtualization extensions for a VM that already uses DDA for VGA passthrough I get a BSOD or an endless boot loop.
