PowerVM Lx86 was a binary translation layer for IBM's System p servers. It enabled 32-bit x86 Linux binaries to run unmodified on the Power Architecture based hardware. IBM used this feature to migrate x86 Linux servers to the PowerVM virtualized environment; it was supported on all POWER5 and POWER6 hardware as well as BladeCenter JS21 and JS22 systems.In contrast to regular emulators only the instructions are translated, not the entire system, thus making it fast and flexible.
