1. A computer-implemented method of facilitating migration of virtual machines within a computing environment, said computer-implemented method comprising: obtaining, by a processor, a current virtual machine to host mapping in the computing environment; obtaining, by the processor, a plurality of future virtual machine to host mappings; obtaining, by the processor, a current migration plan to migrate from a current state of the computing environment to another state of the computing environment; determining, based on the current virtual machine to host mapping and one or more future virtual machine to host mappings of the plurality of future virtual machine to host mappings, that one or more potential alert conditions exist in the current migration plan; displaying at least one of the current migration plan and one or more future virtual machine to host mappings; and adjusting the current migration plan to address at least one potential alert condition of the one or more potential alert conditions to improve processing within the computing environment.
