Re: VM/ESA 2.4 under z/VM 5.x
We had a VM/ESA 2.4 system running as a guest under z/VM 5.1on a z800 z890. No problems.

We haven't tried it. It certainly isn't supported. What hardware are you planning to run on? VM does not virtualize everything (in fact, cannot). z/VM 5.x is supported only on zSeries and System z9. VM/ESA 2.4.0 does not (officially) run on a z9. It might work, especially if you aren't using anything that is hardware dependent. (For example, 370 guests will NOT work.) The last release of VM I can find that was listed (in the GI manual) as supporting VM/ESA 2.4.0 guests is z/VM 4.3.0. The GI manual includes the caveat: In general, an operating system, version, or release is supported as a guest of VM only on hardware (processors, DASD, and other devices) for which support has been announced for that operating system, version, or release to run native, in an LPAR, or as a guest of VM.

Re: VM/ESA 2.4 under z/VM 5.x
Thanks for the input everyone! We're looking at getting off our 9221 box running VM/ESA 2.4 and VSE/ESA 2.6.3. We have merely two VSE guest machines and just a handful of programmers that use CMS for developemnt purposes. No Linux, no productio n VM guest machines other than the VSE guests. In our shop, VM is merely a hyper-visor for our VSE guests. However, our programming staff does not want to lose the various EXEC's they use in CMS and XEDIT. We have a proposal to move to a z/890 processor to run z/VM and z/VSE to stay in support. To ease our migration, I would like to bring up VM/ESA 2.4 as a second-level guest along with one or both of the VSE guests unde r that, and progress from there. Even at the entry level configuration of a z/890, its processing capacity is easily twice that of our current 9221 utilization, so I don't think I need to be too concerned about processing overhead. I've asked IBM about this and I've not been given a definitive answer. Th e latest FAQ that IBM has provided on their z/VM site states that z/VM will run VSE/ESA and VM/ESA as guests. The Tell-All for me would be to find out if anyone has attempted or done this kind of migration. So with that said, if anyone has any further information or experience in doing a migration of this type, I would be very grateful for your input. Thanks again!
Re: VM/ESA 2.4 under z/VM 5.x
Hi Dan: Although you will have a great boost in performance power be careful about the performance expectations of your 3rd level VSE guests. Each time the VSE guest is dispatched you will be running a SIE under SIE (virtual machines are always dispatched in processing mode known as emulation mode - the instruction that places a CPU in emulation mode is Start Interpretive Execution). In long gone releases and hardware left by the curb this killed performance. Strides have been made in this area but a 3rd level production dispatch - better measure it carefully. I have not done this on z boxes - so it may be tolerable. Best of luck and let us on the list know how it goes. What type of CPU usage do you have today?

You could certainly run it under Hercules under z/Linux, although there are probably licensing issues, since presumably VM/ESA 2.4 is not licensed to *that* processor. Adam
