Isolating physical processors during optimization of vm placement

A computer program product for isolating physical processors by processor type during optimization of virtual machine placement, the computer program product comprising:

• one or more computer readable storage media and program instructions stored on the one or more computer readable storage media, the program instructions comprising:
• program instructions to provide a server comprising a plurality of containers and a plurality of physical processors;
• program instructions to build a set of bit masks for each type of physical processor required for a logical partition;
• program instructions to build a set of solution spaces based on the plurality of containers and an amount of each type of container of the plurality of containers;
• program instructions to complete a combinatorial search of the set of bit masks and the set of solution spaces;
• program instructions to identify a solution space of the set of solution spaces for the logical partition;
• and
• program instructions to change a physical configuration and a logical configuration of the server based on the solution space for the logical partition.
