CPU and Host PP/VE license

Hi colleagues,

 

Could somebody discribe me what is the differents between the two type of licenses for PP/VE:

456-110-456

POWERPATH VE HOST LICENSES SRV/USRV=IA

and

456-108-191

POWERPATH/VE STD. X86 T2 (8+ CPUS)=ZC

I know how to use host license but I can only guess how to use CPU one (using for VM with RDMs?).

Any links, documents, descriptions will be appreciated.

Thanks in advance!

Andrey
