3D-acceleration doesn't work on Windows VM

[DarkPro1337]

Hello everyone!
There is a server without built-in video graphics, but with external GPU.
The problem is that Windows virtual machine does not support 3D-acceleration, there are only default video device avalible.
So, question is there are any way to fix this and use external GPU for 3D-acceleration?

hi,

yes you can passthrough the external GPU device using PCI passthrough [0]

please check the link

you'll need to enable "IOMMU" by following the wiki and then configure your VM to include the PCI device, afterwards likely you'll need to install the drivers for your GPU inside the VM

Hi Oguz,

When or how can we also enable 3D acceleration in SPICE?
SPICE is a lot more convenient for me for various reasons and other softwares like VirtualBox and VirtManager offer that feature (3D accel).
Without 3D I cannot run my VMs in an acceptable manner.

Tnx!
