From memory there was LPAR "Logical Partitions" - which were effectively like a VM. and there was WPAR "Workload Partitions" - which had a shared OS and were more like a container.

I had some "interesting" experiences getting stuff to work on WPAR's.

IIRC, WPARs could be just for one process, or full OS (but sharing the resources of one AIX instance, I guess that running on an LPAR or directly in the hardware).

But yeah, bit more like a container.

Then it was probably an LPAR. Are those reliant on hardware magic or just something like cgroups?

LPARs use hardware virtualization. The PowerVM hypervisor (PHYP) is in firmware.
