Discussion on: Hello Newbies in Tech! Try This Powerful Tool by Microsoft to use Linux Effortlessly with Windows OS

If Microsoft breaks their APIs likely to intentionally break the compatibility with 3rd party virtualization software, how is that Oracle's fault?

And you linked to docs.microsoft.com/en-us/windows/w... a page last updated a year ago. A page which still made invalid claims about "recently both VirtualBox and VMware have released versions that support Hyper-V and WSL2" - out of date propaganda. The links on that page also link to VirtualBox 6.0 changelog - and all versions of VirtualBox 6.0 still fail to work under Hyper-V.

It's interesting that maybe VirtualBox has finally managed to fix the compatibility even without Microsoft's help using their proprietary intentionally broken APIs, but this might not be a long-lived solution and there is no sense in building any of your systems to depend now on Hyper-V since there are no guarantees it will not break again in the future.

Also this is far from the only issue with Hyper-V, though it was the most significant one to my work.

People are also reporting that the performance hit is severe, which is unlikely to be accidental.

Yeah, I can confirm the performance hit is severe. Had WSL2 setup and VirtualBox 6.1.6 I was able to start my Win7 VM, but since VirtualBox was forced to use Hyper-V the VM never made it past the Win7 start up animation after 10-15 minutes.

Ended up reverting back to WSL1 to get the performance back on my VMs.

Oh wow, that's worse than I thought .. I was just considering testing it out in the coming weeks for myself - thanks for saving me the effort!
