How does the xVM Server software work?
Sun xVM Server works by providing a hypervisor and control domain that allow differing operating systems to run as guests. The hypervisor can be likened to the spinal cord that provides communication between guest OSs, the control domain, and the hardware. The control domain can be likened to the brain that provides the functionality to create/delete/start/stop guests and also facilitates I/O communication, among other things.
