How can I get my HyperVisor running?

Question

Nearly all Google results tell me to enable it in the BIOS settings of my Lenovo T520i, but the only relevant setting I see there is Virtualisation, which is set to enabled. The Hyper-V manager works alright, and creates a new VM for me, but then when I try and start the VM, I get the "HyperVisor not running" message.

I think this happened somewhere trying to set up a virtual device for debugging Android, and I was asked if the Hypervisor could be turned off, as it interferes with the emulators own virtualisation. I just said, "Yes, get on with it."

Solution

Open a cmd prompt with admin credentials and enter the following:

dism /online /enable-feature /featurename:Microsoft-Hyper-V -All

Have you tried opening a cmd prompt with admin credentials and enter the following: dism /online /enable-feature /featurename:Microsoft-Hyper-V -All

run bcdedit /set hypervisorlaunchtype auto reboot and look if it works now.

Hyper-V is an OS feature, Hardeare Virtualization is a x86 extension and a feature of your hardware, two separate things entirely. Hardware Virtualization also isn't required for a Hypervisor.

@Ramhound VT-x is required ;) "The following items will need to be enabled in the system BIOS: Virtualization Technology - may have a different label depending on motherboard manufacturer." msdn.microsoft.com/virtualization/hyperv_on_windows/quick_st‌​art/…

I did read the question. But was making a general statement it's not always required.
