3.4 PowerVM
The PowerVM platform is the family of technologies, capabilities, and offerings that deliver
industry-leading virtualization on the IBM Power Systems. It is the umbrella branding term for
Power Systems Virtualization (Logical Partitioning, Micro-Partitioning, POWER Hypervisor,
Virtual I/O Server, Live Partition Mobility, Workload Partitions, 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 132.
Note: If you want to move an LPAR that uses Active Memory Expansion to a different
system using Live Partition Mobility, the target system must support Active Memory
Expansion (the target system 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 pre-mobility check phase, and an appropriate error
message displays to the user.
