This is great news. It seems like Apple is still working to make Mac OS a great server platform, which makes sense with the upcoming introduction of the new Mac Pro.

I'd be more inclined to think that they don't want to lose developers to Microsoft after they've announced WSL2 to make stuff like Docker work better.

Docker for Mac and virtualization in general are not something to be proud of in terms of performance.

I used to think so too. Hi use Parallels to run Windows 10 to use Visio 2019. I ran the Parallels hypervisor (the default when you install Parallels) and got the performance I was expecting. After trying a few different things I then went against the advice I read online and sweated the Apple hypervisor. Haven’t looked back since. Performance has been smooth, rock solid, and with barely any fan whirring (which was much more common before).

I’m pretty sure the more recent builds of Docker for Mac can or do use the Apple hypervisor(which appeared in MacOS 10.10). If you haven’t tried it in a while, I’d give it another go.

This change won’t fix that performance as Qemu is slower than native virtualisation. This will speed up ARM emulation. Great for iPhone Simulator, and a potential future ARM Mac.

Qemu supports severel different kinds of emulation, eg on linux it can use KVM for fast virtualization. No clue what apple plans on using though
