Mark, Thanks for the reply. You write: Going back to a previous comment you made, about z/VM not being an option for you. Why is that? z/VM is dirt cheap, and will allow you to run more than one copy of Linux per LPAR, and more effectively share all the resources of that LPAR. Trust me, running Linux in an LPAR is a pain in the neck.
The reason is that this is not an in-house product, and we can't enforce zVM on our customers' production servers. Besides, I understand that running zVM incurs substantial human costs for system administration. Is that your experience too?

Going back to a previous comment you made, about z/VM not being an option for you. Why is that? z/VM is dirt cheap, and will allow you to run more than one copy of Linux per LPAR, and more effectively share all the resources of that LPAR. Trust me, running Linux in an LPAR is a pain in the neck.
