Powervm Live Partition Mobility - IBM Power 595 Technical Overview And Introduction

Notes:
PowerVM LX86 is supported under the VIOS Software Maintenance Agreement
(SWMA).
When using PowerVM Lx86 on an IBM System p POWER6 processor-based system,
only SLES 10 with SP1 and RHEL 4.5 are supported.
Make sure the x86 version is the same as your Linux for Power version. Do not try to
use any other version because it is unlikely to work. One exception is with Red Hat
Enterprise Linux, both the Advanced Server and Enterprise Server option at the correct
release will work.
Although PowerVM Lx86 runs most x86 Linux applications, PowerVM Lx86 cannot run
applications that:
Directly access hardware devices (for example, graphics adapters).
Require nonstandard kernel module access or use kernel modules not provided by the
Linux for Power Systems operating system distribution.
Do not use only the Intel® IA-32 instruction set architecture as defined by the 1997 Intel
Architecture Software Developer's Manual consisting of Basic Architecture (order number
243190), Instruction Set Reference Manual (Order Number 243191) and the System
Programming Guide (order number 243192) dated 1997.
Do not run correctly on Red Hat Enterprise Linux 4 starting with version 4.3 or Novell
SUSE Linux Enterprise Server (SLES) 9 starting with version SP3 or Novell SLES 10.
Use x86 Linux specific system administration or configuration tools.

3.9 PowerVM Live Partition Mobility

PowerVM Live Partition Mobility allows you to move a fully virtualized, running logical partition
between any two POWER6 based servers without a shutdown or disruption to the operation
of that logical partition. A companion feature, Inactive Partition Mobility, allows you to move a
powered off logical partition from one system to another.
At a high level, the required environment to support Live Partition Mobility includes:
Two POWER6-based servers (they can be different models).
An external disk subsystem, capable of concurrent access, and zoned to a Virtual I/O
partition on each POWER6 server.
A running logical partition configured with virtual Ethernet and SCS adapters (no
dedicated adapters).
Sufficient resources on the target POWER6 server so that a new logical partition with
similar resources can be configured.
Figure 3-7 on page 126 provides a visual representation of these requirements.
