Hi Stoyan (@SChalakov ),
A bit update on this Issue.
I have tried to troubleshoot this and also tried what Kevin suggested but with no luck. A bit background is that I am installing a new lab environment and have 2 Intel NUC. I had installed Windows Server 2022 on them and enabled Hyper-V. On that I installed new W2022 Servers and tried to install SCOM 2022 but run into the problem i described.
Today I tried using the same ISO files installing SCOM 2022 on W2022 VM's in the same way in my old environment which is a W2019 Server with Hyper-V. To my surprise everything worked as expected.
I then tried to reinstall one of Intel NUC with Windows 11, enabled Hyper-V and tried to do the installation again in the same way. But got the same errors again and a SCOM that is not working.
So what i did then was to reinstall the Intel NUC with W2019 and then enabled Hyper-V. After that I installed SCOM 2022 on W2022 servers and everything worked as expected.
What I suspect is that there is some thing in Hyper-V in Windows 11 and Windows 2022 that is not compatible with having a guest running SCOM.
Is there anyone else out there which has tried installing W2022 and SCOM 2022 on top of W11/W2022 Hyper-V?
Will try to do an upgrade of W2019 to W2022 and see if I get problems in SCOM afterwards.
