This is a Hypervisor 101 case that keeps showing itself every so often the forums, mailing lists, etc: A message to the effect of “The Hypervisor is not running” when a user tries to launch a VM. Felipe Ayora, one of our awesome UA people, has created this video that steps through how to investigate such a failure and fix it

It really annoys me that this kind of thing is produced in a video.
Lots of enterprises block streaming media, so i'm stuck. What was wrong with KB articles? Grr.
I had the same problem, but a machine boot time go inside the setup hardware and the CPU item change the option Virtualization Enable and Ready.
I have the same issue :( VT and NX Bit are both on and it doesn't work. The hvboot driver and all services are running. I must say that it worked sometime ago and now stopped working for an unknown reason. What next?
ok, I fixed it. I missed the HyperV BCD entry. I copied the VHD with the natively booted Server 2008 R2 from my old Win7 x86 to my newer Win7 Sp1 x64. Please add a better error message that shows in detail what is missing to run HyperV.
