Another reason not to host but keep separate LPARS is DASD.
On Production LPAR, I run all SSD.
On R&D LPAR, I run all 10k SAS.

I'm not sure if you host that you could keep the DASD separate.

It will be a bit simpler to manage if you have the storage to run a hosting partition; the only thing that gets more challenging is applying PTFs. You can do a system save should you need to without taking the guests down.

I've done both and while I try and avoid running a workload it can work in some situations. I have a couple of customers who run a production workload which hosts their dev system and that works well enough for them. If your set up is simple enough this may work for you, but it depends on what is running on those guests. You say you are running production email in one of the guests - I would have though that would want to be running as much as possible.

The safest answer is probably (as others have said) to just run the host partition with no workload.

What is the best practice when running guest partitions - should the
primary be just for the OS and not used for much else..

I want to to have two IBM i partitions one live and the other test for
an RPG application...I also want to set up two Linux partitions
live/test for email and web servers..

Finally can I run any flavor of Linux..
