Virtual Partition Manager.

Virtual Partition Manager
i5/OS now supports virtual partition management to enable the creation and 
management of Linux partitions without an HMC. 
With the virtual partition manager, an i5 server can support one i5/OS 
partition and up to four Linux partitions. 
The Linux partitions must use virtual I/O resources owned by the i5/OS 
partition. 
With the virtual partition manager, uncapped processor partitions can be 
created and up to four virtual Ethernet connections can be defined. 
Dynamic resource movement is not supported. 
Small and medium-sized customers can use the virtual partition manager to 
create Linux partitions for their infrastructure applications. If you want 
to create multiple i5/OS, Linux, and AIX® 5L dynamic partitions, or use 
direct I/O resources and advanced partition management tools, you would 
continue to use the HMC for partition management. 
Virtual Partition Manager is available via PTF MF34753.
