macOS 15.0 supports Nested Virtualization on M3 chips

Asahi Linux supports nested virtualization on Apple Silicon M2, where the feature is present in the chip, but not exposed by macOS.

And ipadOS not even one layer of Mac virtualization

Servers aren't really Apple's thing, so it hasn't been much of an issue, but isn't this something Intel CPUs have supported for almost two decades?

Anyone have a practical case for this? Not complaining just wondering.

I'm not a super-advanced user, so could somebody please let me know if this will allow running Windows on an ARM based Macs? Or perhaps running a VM with macOS Big Sur on macOS 15 ( I'm looking to install a specific version of an app via App Store - a version that is limited to macOS Big Sur )? Thanks in advance!

Still no USB Passthrough it seems. It's a pity.
