I see total eight HyperV related services. HyperV virtual Machine management is the only service running and set to start automatically. Other seven services are set for trigger start and they are NOT running currently.
Which one should I start manually?

Enable Hyper-V in the BIOS / UEFI - every time I've seen this issue it's because BIOS / UEFI doesn't have the appropriate virtualization settings turned on.  Microsoft allows you to install Hyper-V but cannot start it without the features turned on first.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

Ok I will check BIOS in the morning. I set up VMWare on this box last year. But I replaced the MB a couple of month ago and applied all updates and maybe Visualization option is disabled in BIOS by default.

Intel Virtualization SettingYes it was because Intel Virtualization Setting in BIOS was "Disabled". After changing it to "Enabled" & rebooting the server, virtual machine started.

Thank you.

We build on this platform regularly. Make sure to enable _all_ Intel virtualization settings (Intel-vT for example).

Disable C-States and set all performance/fan profiles to PERFORMANCE. These settings will improve things as well.

I have an EE article on Some Hyper-V Hardware and Software Best Practices that may be of further help.
