People may call it bare metal, because there is no virtualized IO (in fact, there is the console), and CPU and memory resources are not shared with other partitions. But there is still a Hypervisor under the OS. It's still a PowerVM LPAR, and boot capabilities still apply as though you were sharing the server with other partitions. Hope that clarifies.
