+
+         Xen is a virtual machine monitor (VMM) or a type-1 hypervisor with support
+         for para-virtualization. Xen can organize the safe execution of several
+         virtual machines on the same physical system with performance close to
+         native. It is used as the basis for a number of different commercial and
+         open source applications, such as: server virtualization, Infrastructure
+         as a Service (IaaS), desktop virtualization, security applications,
+         embedded and hardware appliances.
+         Xen has a special VM called Domain-0 that runs the Dom0 kernel and allows
+         Xen to use the device drivers for the Domain-0 kernel by default.
