Virtual machine could not started because the hypervisor is not running

Hi,

I created a virtual machine "Windows7" on Windows 2012 R2 Hyper-V server box(INTEL R2208WTTYS) When I tried to start the VM, I get an error.
Can you help?

Thanks.

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?

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.

check bios in processor check the virtualization (check box should be selected)

then restart the machine

Yes 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.
