I got this puzzling message on trying to start a vm
Hyper-V Manager
===============================
An error occurred while attempting to change the state of virtual machine
VMAcctg
"VMAcctg" failed to intialize.
The virtual machine could not be started becuase the hypervisor is not
running

"VMAcctg" failed to intialize.(Virtual machine 36.......)

The virtual mahcine could not started becuase the hypervisor is not running
the following action my help you resolve the problem:
1) verify thate the process of the physical computer has a supported version
of hardware-assisted virtualization
*I verified the hw ****Does support *** virutalization assitance
2) verify that the hardware-assisted virtualization and hardware-assited
data execution protedtion are enabled in the BIOS of the physcial computer
and then turn it back on. Resetting the physical computer is not
sufficient.)
* verified*

3) If you have made changes to the Boot Configuration data store review
these changes to ensure that the hypervisor is configured to automatically
* don't understand but I have not change the boot configuartion
since installation *

The virtual machine could not be started because the hypervisor is not
running. The following actions may help you resolve the problem: 1) Verify
that the processor of the physical computer has a supported version of
hardware-assisted virtualization. 2) Verify that hardware-assisted
virtualization and hardware-assisted data execution protection are enabled
in the BIOS of the physical computer. (If you edit the BIOS to enable either
setting, you must turn off the power to the physical computer and then turn
it back on. Resetting the physical computer is not sufficient.) 3) If you
have made changes to the Boot Configuration Data store, review these changes
to ensure that the hypervisor is configured to launch automatically.

Just one point here regarding the BIOS configuration: If you enabled VM
Technology in BIOS, you havee to do a COLD boot of your computer. For some
computers and servers, this means to power off the computer, then turn power
on again. Some other servers do actually do a cold boot by themselves.

One thing that suddenly caught my mind: You have verified that the server
supports virtualization and that this feature is turned on. Does this include
data execution prevention, also known as NX or No Execute Memory Protection?
This feature has to be turned on as well.

somehow after some more windows updates and reboot, it is now working

thank you.

I sitll have a bit of problem some previous version vm and ghost boot iso to
