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?
