Hi,
I´ve got a Windows 10 VM running on my Unraid 7.0.1 server.

A GTX1080 Ti is passed into the VM. In general, this works, but not all the time.

Pretty often, the GPU is not correctly included into the system, leading to a Code 12 error (not enough resources available) in Windows device manager and the Nvidia driver not being loaded.

GPU-Z is detecting the GPU correctly.

The funny thing is, that sometimes the GPU is correctly included and fully usuable after boot-up.

Any ideas where to look at?

EDIT: Another interesting thing I noticed: the vm only gets a network connection when I define VNC as the primary and the GTX1080 as the secondary graphics adapter. As soon as I define the GTX1080 as the primary and I boot up the vm, it doesn´t gets a network connection. It doesn´t respond to a ping and my DHCP server is not getting any DHCP request, so I guess the network driver doesn´t even get loaded.

Thanks,

Hocky

Another observation:

When I remove the NVidia card from device manager and then do a reboot, it gets detected correctly and the Nvidia drivers get installed and I can use it properly.

But after another reboot, I get the issue described above (yellow exclamation mark in device manager and code 12 error).

Hm, no idea? Or did I break a rule that got me on the ignore list? 🫤

This is a very specific issue, so it's probably not easy for anyone else to help, and likely related to the specific hardware being used. Look for a BIOS/firmware update; it may also be worth trying a different PCIe slot if available.

OK, thanks - I´ll try that out.
At least I now know it´s not something obvious.
