Following on from my previous post, I forgot that VMWare doesn’t turn this on by default.
You absolutely require passthrough of the Intel VT-x and EPT bits to the VM if you want to run Hyper-V. As shown in the screenshot below, it’s a quick drop down setting. You require this in addition to the .vmx file configuration change.
When using VMware Workstation 10 be sure to select the option [Virtualize Intel VT-x/EPT or AMD-V/RVI]. This is needed as well to install Hyper-V within the virtual machine.
