Windows 10: Hyper-V fails to run a virtual machine saying hypervisor*isn't running

Hi all,

Title says it all. I'm using Win10 Enterprise edition Insider Preview 15007 on an Intel Core 2 duo based notebook with 4gb ram. When I tried hyper-v some months ago, it succeeded.

I don't know why it doesn't run. Intel Virtualization Technology is on according to Intel Processor Identification Utility. At least some*months ago, it worked.

What's wrong?

Thanks in advance.

:)

 

Hyper V: How to install guest operating OS?

Internet? Examples:

How to Create and Run Virtual Machines With Hyper-V

Cannot turn off Hyper V, cannot run Virtual Box machines or VMWare machines

Since the latest update:

Edition: Windows 10 Pro

Verion: 1607

OS Build: 14393.222

I can no longer turn off Hyper V and thus cannot run Virtual Box machines or VMware machines.

When I attempt to turn off Hyper V and restart Windows as requested, Windows simply re-enables Hyper V.

Then when I try to run a Virtual Box machine, I get an error like this:

Failed to open a session for the virtual machine Centos 70.

VT-x is not available (VERR_VMX_NO_VMX).

Result Code:

Component:
ConsoleWrap

Interface:
IConsole {872da645-4a9b-1727-bee2-5585105b9eed}

When I try to start a VMware machine, I get this:

VMware Player and Hyper-V are not compatible. Remove the Hyper-V role from the system before running VMware Player.

But as I have noted, I am not able to turn off Hyper-V since the Anniversary Update.

Any suggestions would be greatly appreciated.

 

see tutorial on how to setup hyper-v in tutorial section. In section 2 (I think) is a bcdedit command you need to run, then reboot.
