If you already have z/VM in-house, this decision is literally a no-brainer. Use z/VM.
The FAQ you reference, while very basic, is still correct. After using z/VM to run Linux guests, trying to do it in an LPAR feels like I'm blindfolded with both hands tied behind my back. Additionally, all the reasons people are looking at VMWare and Xen on midrange systems, are the same reasons why this community has been running Linux on z/VM from day one. They're just now starting to figure out that virtualization is a good thing. Some of us have been doing it for over 30 years. If you don't have z/VM already, the list of "cons" is pretty short: - The cost of a z/VM license (very inexpensive compared to other costs) and associated management and performance tools. - A (typically) 3%-5% performance hit for z/VM overhead.

So we can go natively in a LPAR or under VM (or both of course). Can you route me to some doc or provide us with some pointers about the pro's & con's in this LPAR-vs-VM issue? And please of a lot of more & higher quality than the very basic http://www.marist.edu/linuxvm/faq.html (I don't agree at all with: The discussion of “why VM” is in the FAQ, http://www.marist.edu/linuxvm/faq.html, and it should be referenced before rehashing old discussions.) jan ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
