Your question implies that you’re probably the best-suited person to make it work.
PhotoLab for other operating systems has been requested for quite a while.
Nevertheless, it’s only available for Windows and macOS as of now. Considering the limited resources of DxO, I don’t expect any effort and support for platforms on which most applications are free.
But again, if you can make it work, there’s a bunch of people eager to read your how-to, I suppose.
From what I understand, a GPU being made available to a VM requires that the host OS and GPU both support PCI bifurcation. The best place to inquire about this would be Level1Techs as Wendell, their resident genius, works on this a lot.
I don’t think Virtual Box supports GPU pass through which would be a problem with anything requiring the GPU acceleration. This information may be out of date as it’s some time since I explored Virtual Box.
I would suggest that KVM may be a better option as it will support pass through for AI workload applications.
I haven’t tried this for PL on Windows as a VM hosted on Linux, but I do use KVM when virtualizing Linux instances with GPU hosted AI workloads.
Don’t need binary pass-through these days. It’s still required to utilize the newer ‘neural’ AI coprocessors but not (I think) for access to GPU computing resources.
I believe that we just need reliable OpenCL/GL API access to the hardware.
