You can configure more than one virtual processor or CPU for a virtual machine using VMware Virtual SMP for ESX.

If the virtual machine is on an ESX/ESXi host, you can configure a virtual machine to have up to eight virtual processors or CPUs. Virtual machines cannot have more virtual CPUs than the actual number of logical CPUs on the host—that is, the number of physical processor cores if hyperthreading is disabled or two times the number of physical processor cores if hyperthreading is enabled. For more information about using SMP, consult the VMware Knowledge Base.

Note

Not all guest operating systems support SMP, and some that do require reinstallation if the number of CPUs changes.
