Windows VM, Linux Host (API: None)

Open pringithub opened this issue 5 years ago • 2 comments

Hello -

Not an issue I'm expecting resolved, but just leaving this here for anyone else who is curious.

I'm running an Ubuntu 16.04 computer with a Windows 10 VM through VirtualBox in an attempt to get a RenderDoc capture. The API says none. Looking further, Task Manager reveals that there is no GPU attached. I'm assuming the virtualization layer abstracts the GPU away such that the VM can't use it directly ..

Did you try to enable 3D Acceleration in Virtual Box' settings? Do you have several GPUs on your machine (e.g. if you use a modern high end laptop you have both a proper GPU and the integrated chip)? The browser running within the VM still has to let the true GPU know of the things to draw, even though it is through a software emulated GPU renderdoc could be able to see it.

Good call on 3D acceleration. It was in fact unchecked, however, after checking that box and starting the VM, the GPU is not recognized.

I have an NVIDIA Quadro M5000M using 418.67 proprietary driver version. It appears to be the only GPU (confirmed with lspci | grep -i --color 'vga\|3d\|2d').

I agree with your last statement, however I don't have the time at the moment to look into how the virtualization layer works here ..

Merci
