For all supported configurations of 32-bit and 64-bit host and guest operating systems running on multiprocessor host machines, VMware Server supports two-way Virtual SMP. This enables you to assign two virtual processors to a virtual machine on any host machine that has at least two logical processors or is a uniprocessor machine with hyperthreading enabled.
Note: On hyperthreaded uniprocessor hosts, performance of virtual machines with Virtual SMP may be subpar.
Under Processors, you can select the number of processors for the virtual machine. Guests with more than two virtual processors are not supported in VMware Server.
If the host is a uniprocessor machine (and is not hyperthreaded), assigning two processors is neither supported nor recommended. A warning message appears. You can disregard this message and assign two processors to the virtual machine, but once you have finished creating the virtual machine, you will not be able to power it on unless you move it to a host machine with at least two logical processors.
