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.
I'll echo this for anyone else in the comments -- You can watch the cricket episode with 0 knowledge of the show and 0 knowledge of cricket. If you haven't ever seen Bluey - it's a great example as to why so many speak so highly of it. If you haven't seen bluey but want to see what the fuss is (and especially if you have any interest in sports) -- it's only 7 minutes long and absolutely worth watching.
