The NetScaler Gateway VPX setup for the Microsoft Hyper-V platform requires Windows Server 2008 R2 with the Hyper-V role installed. Like all virtualization systems, Hyper-V enables you to create a virtualized computing environment that results in better usage of your hardware resources.
Hyper-V is a type 1 hypervisor that comes preinstalled with Windows Server 2008 R2. It needs to be enabled as a role on the Windows Server.
