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, 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 binary translation software, which allows Linux applications compiled for the Intel x86 platform to run in POWER-emulation mode. A supported Linux distribution was a co-requisite for use of this feature.
IBM PowerVM comes in two editions:IBM PowerVM Standard: supported on all POWER6, POWER7 and POWER8 systems. Unrestricted use of partitioning – 10× LPARs per core . Multiple Shared Processor Pools. This is the most common edition in use on production systems.IBM PowerVM Enterprise: supported on POWER7 and POWER8 systems only. As PowerVM Standard, but with the addition of Live Partition Mobility and Active Memory Sharing.
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, limited to three partitions, and with no support for Multiple Shared Processor Pools.
