The Create Capacity Configuration for Linux on z Systems fixlet is relevant on all computers where manual configuration is required. It is not relevant on computers where automatic capacity configuration is supported. If the fixlet is not relevant, you do not have to perform any manual actions to calculate the capacity values.
Automatic capacity configuration is supported on Linux on z/KVM and on System z10 E64 (type 2097) mainframes with z/VM 6.3 that supports the Store Hypervisor Information (STHYI) instruction.
