Not sure about that, except if their phrasing is astonishingly poor, which is of course possible. I mean, in my book "Linux 4.19 kernel shipping in Windows" means a Linux kernel shipping in Windows, and that would need Hyper-V (Linux is trademarked btw, MS can't just pretend that they ship a Linux kernel if they don't). At the same time, I really hope that this is not the case and that it actually means that they are targeting a syscall compatibility with Linux version 4.19; because I'm certainly not gonna give up my third party VMs for some work, so if WSL is rebased on Hyper-V that means bye-bye WSL for me.

Rewriting WSL to suddenly require a VM would be a HUGE leap backwards and I can't see that being the solution chosen. It doesn't make sense.

Adding the appropriate things to WSL to make Docker for Windows no longer require the Moby VM, or to support Linux Docker within the WSL environment without modification, is an approach that makes much more sense to me.

It appears that is what they have done though: https://devblogs.microsoft.com/commandline/shipping-a-linux-...

Show me where in that article it says that a VM is required. Am I interpreting you incorrectly?

This article was linked from another article which I guess is where I saw the VM info:

> WSL 2 uses the latest and greatest in virtualization technology to run its Linux kernel inside of a lightweight utility virtual machine (VM). However, WSL 2 will NOT be a traditional VM experience.
