4. In the Processors list, choose the number of virtual CPUs in your virtual machine.
You may choose 1 or 2 virtual CPUs, but they must be less than or equal to the
number of physical CPUs on your server.
Note: Some guest operating systems, such as Windows NT, can be configured
with a single processor only. If you are configuring such a virtual machine, a note
indicates this and you cannot select more than one virtual CPU.
Note: You can create dual-virtual CPU virtual machines only if you have
purchased the VMware Virtual SMP for ESX Server product. For more information
on this product, contact VMware, Inc. or your authorized sales representative.
The default setting in the Memory entry field depends on the guest operating
system you have selected. You may need to change it to meet the demands of
applications you plan to run in the virtual machine. You may change this setting
later, on the virtual machine’s Memory tab in the management interface. See
Managing Memory Resources from the Management Interface on page 410.
For background on allocating memory to virtual machines, see Sizing Memory
on the Server on page 424.
