Xen VPS benefits can run on two different types of guests (also known as domUs or unprivileged domains), Xen Paravirtualization (PV), and Xen Full Virtualization (HVM). Both of these can be used together on a single Xen system. Unlike OpenVZ, Xen can also be utilized for both Linux and Windows, with Xen PV supporting Linux and Xen HVM supporting Windows.
