You should be aware of certain limitations before you move a virtual machine to a different host system.
The guest operating system might not work correctly if you move a virtual machine to a host system that has significantly different hardware, for example, if you move a virtual machine from a 64-bit host to a 32-bit host or from a multiprocessor host to a uniprocessor host.
Player 3.x and later virtual machines support up to eight-way virtual symmetric multiprocessing (SMP) on multiprocessor host systems. You can assign up to eight virtual processors to virtual machines running on host systems that have at least two logical processors. If you attempt to assign two processors to a virtual machine that is running on a uniprocessor host system, a warning message appears. You can disregard this message and assign two processors to the virtual machine, but you must move it to a host that has at least two logical processors before you can power it on.
You can move a virtual machine from a 32-bit host to a 64-bit host. You cannot move a virtual machine from a 64-bit host to a 32-bit host unless the 32-bit host has a supported 64-bit processor.
