In order for MVS to bring a new CPU online, it must be in the
configuration ("Reserved"?) when the guest IPLs (as it is in an LPAR
activation profile). CP does not virtualize this processor state.
The "max CPUs" specification on MACHINE is just an authorization mechanism
rather than a virtual machine architectural attribute.
