In virtualization terminology, Logical Domains (LDom) is a technology for server virtualization that enable users to allocate system resources, such as memory or devices into logical groupings in order to create multiple virtual machines. Each of these virtual machines can use its own operating system, have its own resources and also be identified as a single stand-alone unit within the computer system. LDom is a free Sun virtualization technology and is supported on Sun servers which utilize UltraSPARC T1 or UltraSPARC T2 processors, running at least Solaris 10 11/06 and the latest server firmware.
