3.4 PowerVM
The PowerVM platform is the family of technologies, capabilities, and offerings that delivers
industry-leading virtualization on the IBM Power Systems. It is the umbrella branding term for
Power Systems virtualization (Logical Partitioning, IBM Micro-Partitioning®, POWER
Hypervisor, Virtual I/O Server, Live Partition Mobility, and more). As with Advanced Power
Virtualization in the past, PowerVM is a combination of hardware enablement and
value-added software. The licensed features of each of the three separate editions of
PowerVM are described in 3.4.1, “PowerVM editions” on page 86.
Moving an LPAR: If you want to move an LPAR that has Active Memory Expansion
enabled to another physical server using Live Partition Mobility, the target server must have
Active Memory Expansion activated with the software key). If the target system does not
have Active Memory Expansion activated, the mobility operation fails during the premobility
check phase, and an appropriate error message is displayed.
