Recently I have prepared a windows server 2008 Operating System in Dell machine and configured the hyper-v role. When I am trying to start a virtual machine from a physical host it prompted “the virtual machine could not be started because the hypervisor is not running” error. So I’ve completed a little research and following are the steps to get to the bottom of the Hyper – v problem.
- Open command prompt with run as administrator and run below command.This should put the Hyper-V driver back into the launch procedure bcdedit /set hypervisorlaunchtype auto
- Reboot the server and hit F9 to enter the Bios.
- Go to Advanced options > Processor Options
- Find the “No-Execute Memory Protection” and enable it. (Hit enter)
- Find the “Intel(R) Virtualization Technology” and enable it. (Hit enter)
- DEP enabled in BIOS
- Security > Execute Disable (set to On)
- Performance > Virtualization (set to On)
- Performance > VT for Direct I/O Access (set to On)
- Performance > Trusted Execution (set to Off)
- Save and exit using F10
Now you can able to start the Virtual machine normally. Please comment if you face still issue.
Note: If you run Windows 8 or Windows server 2012 virtual machines in windows server 2008 or Windows server 2008 R2, you can see below issues.
- The virtual machine stops responding
- You receive a Stop error message, and the computer restarts. This behavior stops all running virtual machines together with the computer.
The issue occurs because the Hypervisor does not handle the one-shot synthetic timer correctly.
So to resolve this issue you need to run below the update
