Yes, that would be the exception. In fairness there are a few IBM products
charged according to full capacity, but all the ones I've run into are

Assuming VWLC, I'm trying to figure out why that would be true. I could see
how running some Linux workload on CPs might cause z/OS software charges to
*decrease*, though.

To the question of DASD type. For Linux you can user either CKD or FBA.
But for z/OS you have to use CKD. z/OS does not understand FBA disks.

Almost everything is REALLY FBA now. DS8xxx, DS6xxx, etc. All FBA, doing
CKD emulation. z/VM and z/VSE give you the option to use it as FBA and
remove the CKD emulation layer.
Come on z/OS, get with the program.

Is it possible to have both z/OS and Linux on same z/VM? If so
which volume type I have to use (either FB or CKD). In some IBM

Thanks Regards,

A single LPAR can't have a IFL and a CP.

On the System z10, this restriction is removed by using something new
called a z/VM-mode LPAR (a.k.a. z/VM Image Mode LPAR). Such an LPAR
can contain almost any mix of CPs, IFLs, zIIPs, zAAPs, and/or ICFs and must
run z/VM as the base
