Unsupported virtualizations

■ System Z� relative weights - not supported by ILMT, not

eligible for Sub-Capacity

■ x86� Resource pools settings to Virtual Manager

– not supported, not eligible� Mixing OS limits with any other virtualization

– not supported, not eligible� Mixing Bios limits with any other virtualization

– not supported, not eligible� Xen – not supported by ILMT, however some

flavours are eligible for Sub-Capacity, please refer to below linked document

Conclusions

■ Sub-Capacity License Counting Rules are well-defined and described on clear examples

■ ILMT calculates PVU strictly according to Sub-Capacity License Counting Rules

■ Manual calculation and ILMT calculatoion of used processors must give the same results

■ Manual calculation is available in a few cases as a replacement of ILMT
