Re: System i LPARs

Hi, guys:
VMWare only runs on Intel platforms, and can only virtualize Intel virtual machines.
In the same vein, the "father" of LPARs was VM/370 -- that OS created multiple System/370 virtual machines on a single host IBM System/370.
That's why you must run a Linux PowerPC distribution on iSeries or pSeries LPARs, and not just your "garden variety" Linux distro. for Intel.
You could run VMWare on the IXS card, and then run Linux or Windows under VMWare on the IXS, and you would be able to use the "virtual DASD" and "virtual Ethernet" etc. provided by OS/400 or i5/OS ...
Or, you could run an "emulator" like Bochs or QEMU, that allows to emulate a different processor architecture than the underlying hardware, but the overhead for doing so is usually so great that this is really only of "academic interest." 

Does that "make sense"?

Cheers,

Mark S. Waterbury

Pete,
OK Now you got me wondering. I love the concept of virtualization but which tool are you using to run windoze on a System i Linux partition? Maybe I've been sleeping under a rock but the procesors are 'significantly different' so I hadn't thought this to be possibe?

A total virtualization convert! I love it! So get your head around this one. Run a Linux LPAR and then put VMWare or some other virtualization engine on it and run Windows on that. Theoretically possible. Blows the mind...
We have two customers running Linux LPAR's (SUSE) and use it for web serving. Works like I champ and I took a snapshot of the server when it was stable and I can always restore that image if I need a quick recovery.
