I installed 2008 R2 on a Dell Optiplex 755, 2.33Ghz Core 2 Duo, 2GB Ram. This is not in a production environment, just used for learning purposes.
I installed the Hyper V role and it installed fine but there is a red X in Server Manager on Hyper V. Event properties show hypervisor driver required by the Virtual Machine Management service is not installed or is disabled. I have tried to follow these instructions, but I do not get those options.
On the first screen shot I do not have the Intel AMT Configuration option. This might be why I cannot enable Intel AMT. I have updated the BIOS and reinstalled the chipset drivers. I am lost at this point.
