Is GPU passthrough possible on macOS VMs?

[samwyndham]

Hi,

I would like to know about tarts support for GPU passthrough on macOS VMs. By GPU passthrough I mean that which is discussed on this webpage:

https://www.macstadium.com/blog/gpu-passthrough-virtualization-with-mac-private-clouds

Specifically I would like to know:

1. Does tart currently support GPU passthrough. If so how would one set it up?
2. If not, would a future version of tart likely support it?

The reason I would like to setup GPU passtrough is to test code that utilizes Apples metal APIs (via Xcode) .

Thank you!

Hey Sam,

Tart already supports paravirtualized GPUs thanks to 'Virtualization.Framework'. You can use Metal APIs inside the VMs with no additional setup.

I'd recommend to use Ventura guest for your experiments since Apple folks drastically improved GPU support in the latest release comparing to Monterey.

Thanks @fkorotkov good to know. I will play around with a Ventura guest as you suggest.
