I would not recommend to configure guests with a larger SMP than the underpinnng physical infrastructure provides backing for, i.e. if there is only one CPU available to VM the guests should also be uni- processor guests only. If you want/need to exploit SMP in guests based on workload requirements VM should also have at least as many processors available to itself and hence be able to dispatch to its guests as required. > > We run DB2 on 8 Linux virtual servers w/ z/VM.

May be useful if you have a larger SMP than you want DB2 to use, but why would you configure a larger SMP to it than available?
