The traditional implementation of Workstation Pro relies on direct access to specific hardware features of the x86 microprocessor.
These features, generally called Intel VT or AMD-V, are also used by recent versions of Windows that support Hyper-V. Also, it is not possible to run traditional Workstation Pro on a Windows host with the Hyper-V capability enabled because some Windows features like the virtualization-based security (or VBS), are built on top of Hyper-V. Therefore, a VBS-enabled Windows host is also incompatible with traditional Workstation Pro.
