Description

IBM PowerVM has the following components: * A "VET" code, which activates firmware required to support resource sharing and other features. * Installation media for the Virtual I/O Server (VIOS), which is a service partition providing sharing services for disk and network adapters. Prior to its withdrawal from marketing in 2011, PowerVM also came with installation media for Lx86,

x86 x86 (also known as 80x86 or the 8086 family) is a family of complex instruction set computer (CISC) instruction set architectures initially developed by Intel, based on the 8086 microprocessor and its 8-bit-external-bus variant, the 8088. Th ...

(which allows running virtual machines to migrate to another system) and Active Memory Sharing (which intelligently reallocates physical memory between multiple running virtual machines). Prior to its withdrawal from marketing in August 1, 2014, a third edition, IBM PowerVM Express, was also available. Intended primarily for "sandbox" environments, it was only supported on "Express" servers (e.g. Power 710/730, 720/740, 750 and Power Blades), limited to three partitions (one of which must be a VIOS partition), and with no support for Multiple Shared Processor Pools.
