Linux Only indicates using IFL's only which are not kneecapped like a GP engine 
may be.  My IFL's are dedicated to the LPAR, unlike the Shared GP engines.

The Linux-only option is not new. Our z12 and z196 Linux-under-VM LPARs are 
defined with the 'LINUX only' option. I don't recall an explicit reason for the 
recommendation.

That certainly used to be true, but I'm not at all sure it still is the case.  
If I'm remembering right, z/VM licensing is the same for both CPs and IFLs.  
It's just that if you _do_ have a machine with both and you create a z/VM mode 
LPAR, then the z/VM licensing algorithm includes _all_ those processors instead 
of just CPs or just IFLs.
