No, PCI-E passthrough is not enabled on non-Server, and you arguably wouldn't do this on a Windows hypervisor. anyways, you'd do it with a Linux+KVM hypervisor

No, PCI-E passthrough is not enabled on non-Server, and you arguably wouldn't do this on a Windows hypervisor. anyways, you'd do it with a Linux+KVM hypervisor for either Linux or Windows guests. Using GPU passthrough, however, is allowed. WSL2 does this by using the existing Mesa/DRI/DRM open source stack, but instead of a GPU-specific DRM driver, it is one that speaks WDDM (the DRM equivalent in the Windows driver stack), and only requires a GPU-specific ennoblement package (provided by the vendor, and matches the Windows driver it is talking to; AMD, Nvidia, and Intel all ship one inside of WSL2).

> No, PCI-E passthrough is not enabled on non-Server, and you arguably wouldn't do this on a Windows hypervisor. anyways, you'd do it with a Linux+KVM hypervisor for either Linux or Windows guests. If it was enabled on Pro, I would use PCI passthrough. I use hyper-v for a Linux dev environment on a windows workstation. My NIC supports virtual functions, so if I could passthrough one to the dev VM, I wouldn't need software bridging and that might be nice. (OTOH, I don't know if my motherboard has reasonable passthrough groups and all the other stuff that makes passthrough never work for me)

  And why you not run Linux dev env on bare metal and avoid the pain of using W11 ?

    I think part of the answer is that if you're going to use both it's nicer to use Windows with Linux as the guest than the reverse. MS clearly put a lot of effort to make the integration nice and it shows. Like how Parallels on macOS makes Windows a very nice guest. If there was software that made Windows as seamless on Linux I bet it would get a lot of use.

    I don't want two computers for work, and I'm not getting paid enough to fight with Linux GUI. I can do all the work without Linux GUI and have a working desktop (still W10 for now). I just need a VM to get a close enough match to prod VM.
