Hyper-V and VMWare Incompatibility
Some ITC courses require the use of Microsoft's Hyper-V (notably the Microsoft Server courses), other courses require VMware Workstation (notably CCNA Voice to run the CUCM and CUC software). Windows 8 also includes Hyper-V so it is more likely to find it enabled on clients in the future.
If you try to install VMware on a system which already has Hyper-V installed you will get an error stating that they are incompatible. In this case you have two choices...
Option 1: Remove Hyper-V
If you do not need access to Hyper-V and VMware at the same time the cleanest thing is to only have one installed at a time. You can remove the Hyper-V feature/role from your system as described below.
Removing Hyper-V from Windows 8
- Open the Control Panel
- Open the Programs and Features section of the control panel
- Navigate to "Turn Windows Features On or Off"
- Make sure all Hyper-V components are unchecked as shown below.
- Click "OK".
- Close all windows.
Option 2: Create a Boot Option Environment
You will not be able to run VMware and Hyper-V at the same time. However, it is possible to have them both available on the same system and switch back and forth between them using a simple reboot of the system. The instructions below are based on the information which can be found here, here, and here.
