Windows still does not support sub virtualization on amd hardware. I.E you cannot use kvm in wsl. Why would you want to? Testing in clean environments. Microsoft also does not allow vmware to use AMD-V if you have WSL or hyperV enabled. I believe that is also an effect of sub virtualization. There's currently plenty of bugs wherein if you use vmware without amd-v things like disk encryption don't work (fedora 34, ubuntu 20.10 etc). Microsoft continually says "they're working on it" but it's been a long while and it's obvious they have other priorities here. AMD ryzen cpu's have been the superior CPU for a while now, methinks there's lots of handshakes between intel and microsoft.

  Hi. I'm a customer who would like to ask for this. Where can I do it?

    GitHub issue, or your Microsoft account rep.

    If you have to ask you're not a big enough customer.

Support for nested virtualization on AMD processers is now available! You can see this blog post for more info: https://techcommunity.microsoft.com/t5/virtualization/amd-nested-virtualization-support/ba-p/1434841 https://techcommunity.microsoft.com/t5/virtualization/amd-ne...

  You made my day! So excited to try this

  It's not included in current stable releases. Have to be on insider build, which collects all manner of system and user data. https://github.com/microsoft/WSL/issues/4193 https://github.com/microsoft/WSL/issues/4193

    Yeah, this sucks massive monkey balls. That being said, I really want easy GUI emacs on WSL, specifically because I'm stuck on Windows for work. So, I've signed up for this at home to figure out how it all works. I'm not happy, but this is the world we live in I guess :/.
