Enable Hyper-V under VMware workstation
When you try to install Hyper-V under VMware workstation, it will not allow you to add Hyper-V feature for your practice lab. You will receive a message “The validation process found problems on the server to which you want to install features. The selected features are not compatible with the current configuration of your selected server. Click OK to select different features.” as below:

So, how to practice? No problem. You can configure this in vmx file of vmware work station.
Let’s get started to allow our Windows 2012 Datacenter server to add Hyper-V feature.
- Locate the .vmx file for the new VM, and edit the .vmx file using notepad, add below strings to the last line
hypervisor.cpuid.v0 = “FALSE”

2. Shutdown the VM and go to Virtual Machine Settings -> Hardware ->Processors and select Intel VT-x/EPT or AMD-v/RVI and select Virtualize Intel VT-x/EPT or AMD-V/RVI.

3. Power on the VM and try Adding Hyper-V feature. Hope you will try this in your practice lab only and not in Production.
