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...
Eight months have gone by. Has this been fixed by Microsoft? I still have all efficiency cores disabled because of this.
The PC I would like to use as a lab & test - Lenovo M90q Gen3 with i7-12700 does not even have the possibility to turn off efficiency cores in the BIOS, so I am stuck with a great machine with 64 GB fast DDR5 RAM and no chance to use Hyper-V, which is a real bummer. Wish there were some information on whether any updates to Windows 2022 will address the problem...
Ronny Röe The only option on running a VM, is use Windows 11. Enable the Hyper-v feature.
In Windows 11 you can use all Cores there is no need to disable the cores. But Windows 11 is not Windows Server 2022.
- Thanks Robert for the reply.
I will try to find time to re-install with Windows 11 and check if it works. I thought though that most of the core code is shared between Windows 11 and Windows 2002, so it would behave the same way? Anyway, do you think that Microsoft will have an update any time in the future for Server 2022 to support Intel CPU's with a mix of "standard" and "efficiency" cores? Someone wrote that Intel plan to also introduce this to server-style CPU's like Xeon as well and then I guess it has to be addressed?- Don't think there will be an update that this will be fixed. I also came from server and running now Windows 11 and hyper-v the only down side of this configuration is you can't use the server components direct with hyper-v that means storagespaces direct for sample, for me this is a huge bummer, as the setup is not to expensive and you can test or run a lot of configuration setups.
For now work with Windows 11 and you will see it is not that bad 😉 hyper-v works perfectly and the VM's runs fast on nvme storage
