+
+ 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.
