Asahi said it's present in M2 hardware, will likely be supported in future MacOS.

  Asahi Linux is introducing support for some brand new Apple Silicon features faster than macOS.. M1 has a virtual GIC interrupt controller for enhanced virtualization performance. Linux supports it, macOS does not.. M2 introduced Nested Virtualization support. The patches for supporting that on Linux are in review; macOS still doesn't support it.

Thanks for link, that is very exciting if it works as expected.

Curious what will enable this in M2 vs M1. Looking at https://developer.arm.com/documentation/102142/0100/Nested-v... it appears to indicate nested virtualization is in Armv8.3-A and both M1 and M2 are ARMv8.5-A according to https://en.wikipedia.org/wiki/Apple_M1 and https://en.wikipedia.org/wiki/Apple_M2

Will be interesting to see what other arm cpus gain this with the Linux patches.

Have you used (non-nested) virtualization at all on Asahi? If so what is your experience with performance and overall thoughts so far?

Apple appears to have a one of a kind special license for ARM (due to being a founder of the company) so they can pick and choose otherwise "required" extensions to support and add their own extensions as well. You can't directly compare an Apple design to a specific ARM version because of this.
