IBM 3650 - Hypervisor is not running

by Jacob Laue Petersen 8. June 2010 12:41

Today I came across this somewhat “classic” error when deploying a new Hyper-V server. When firing up a VM you receive this error message: An error occurred while attempting to start the selected virtual machine(s). In details it says that the hypervisor is not running.


When receiving this error please make sure that…

  • Hyper-V server has been powered down and up after adding the Hyper-V role. A simple restart won't be enough.
  • Bios settings is correct. This is a sample from an IBM 3650 (Intel proc). Enable “Execute Disable Bit” and enable “Intel Virtualization Technology".

A sample from AMD based proc will followSmile
