The vswitch CPU count semantic check is being modified to reduce the
minimum acceptable value from 1 to 0. This is being done to accommodate
work being done to allow a vswitch to share the set of platform CPUs and
operate in a reduced CPU usage mode rather than require a dedicated set
of CPUs to run.
