Alder Lake 12th Gen Intel CPU won't boot on Windows Server 2022 with HyperV enabled

My PC has 12700K, ASUS Z690 mainboard, 64GB DDR5,  and Samsung 980Pro. I'm trying to run Windows Server 2022 on it, but it will not boot when I enabled Hyper-V. It will boot fine without Hyper-V role...

upwander Hello, I'm in the same boat thinking about buying an i9 for a 2022 server. Has anyone tried to set affinity only to P processors for Hyper-v?

      Sorry, I mean all processors active by default and apply affinity for Hyper-V only to P processors. This way the server would work with all processors and use only the P cores for Hyper-V. Are you referring to this scenario or do you have the E cores disabled all the time?
