Hi,

I'm looking for some official info about whether or not Hyper-V in Windows 11 supports the 12th gen Intel CPUs. These CPUs have two sets of cores, Performance (P) and Efficiency (E).

I have read things on some other forums that seem to suggest that Hyper-V does not understand these new core layouts and that you have to disable the E cores in the machine's firmware in order to enable Hyper-V to work.

Can anyone confirm or deny this? I'm currently having to delay buying 12th gen CPUs until I know that this works properly.

Thanks.

This is important for me as well as no Hyper-V support would make new 12th gen devices useless for me.

From what I know:
.) It is still broken under Server 2022 and below if E cores are enabled
.) It should work if e cores are disabled, but most OEM devices do not have this option in BIOS. Also this would turn most U series laptops into Dual cores so not really an option
