The processor on this computer is not compatible - Hyper-v on virtualbox

Today i am going to discuss a small issue that i have experienced while working on my test lab on virtual box.

I was trying to add a role "Hyper-V" on windows server 2008 R2 and was getting this error.

Hyper-V cannot be installed

The processor on this computer is not compatible with Hyper-V. To install this role, the processor must have a supported version of hardware-assisted virtualization, and that feature must be turned on in the BIOS.

Then I checked BIOS setting and virtualization option was already enabled there.

Then after doing some research with brother Google I finally found a very easy method.

Method1 : Step One, Run Command prompt as Admin  and enter command

Dism.exe /online /enable-feature /featurename:Microsoft-Hyper-V

And restart server.

Now you should see Hyper V role, If no then go for Method 2

Method 2:

Again open cmd as Admin and paste this command

Dism.exe /online /enable-feature /featurename:Microsoft-Hyper-V /featurename:Microsoft-Hyper-V-Management-Clients

Tadaaa…

There you go. Issue resolved. Now you can configure Hyper-V and move on.
