Our review
Pros	Moves active or inactive logical partitions between servers with Live Partition Mobility Micro-partitioning and Virtual I/O Server support processor, storage and network sharing Offers management through HMC, NovaLink, PowerVC and OpenStack services	Supports paravirtualization and hardware-assisted virtualization. Offers VM checkpoints, migration, nested virtualization, and PCI passthrough. Integrates with XAPI, libvirt, and QEMU; includes the xl command-line toolstack.
Cons	Designed for IBM Power Systems rather than general-purpose server hardware Requires contacting sales rather than choosing from a public price list Management spans several tools, including HMC, NovaLink and PowerVC	VM management through the core interface uses the xl command line. Nested HVM is documented as experimental. Community support and documentation are the listed support channels.
