Hello Folks,

I Installed Hyper-V on Server 2012R2 (with GUI) and on the HP DL-380p server host and then enabled "No-Execute Memory Protection", "Intel Virtualization Technology", and tried enabling and disabling "Intel VT-d". I continually get the error message below when I try to power on any machine. Any idea what I am doing wrong?

Hi,

Make sure DEP and CPU virtualization is enabled in BIOS.  Run below command and reboot the server.

bcdedit /set hypervisorlaunchtype Auto

Hope, it will work for you.

I had this happen to me once and even when I set the bcd store entries
bcdedit /set hypervisorlaunchtype Auto

Open in new window

the only solution was an over install.

I think, no need to reinstall the OS. Just remove the Hyper-V role and install it again will resolve this issue.

David,
You had this issue with fresh installation of Hyper-V or server which worked as hyper-v for long time?
