Each virtual machine has a standard virtual hardware configuration for chip set, BIOS, ports, and so on. The amount of memory and number of processors depends on your Mac.

One virtual processor on a host system with one or more logical processors

Up to eight virtual processors (eight-way virtual symmetric multiprocessing, or Virtual SMP™ ) on a host system with at least four logical processors

The following configurations have two logical processors:

A multiprocessor Mac with two or more physical CPUs

A single-processor Mac with a multicore CPU

Intel 440BX-based motherboard



PhoenixBIOS 4.0 Release 6 with VESA BIOS

Up to 8GB, depending on your Mac's available memory, virtual machine hardware version, and guest operating system support

Total memory available for all virtual machines is limited only by the amount of memory on the Mac


If you assign too much memory to your virtual machines and have them all running at the same time, your Mac might slow down because of heavy disk swapping. As a best practice, make sure the total memory that VMware Fusion and all running virtual machines uses stays below 70% of your total Mac memory.



128MB 3D accelerated video with DirectX 9.0c with Shader Model 3 and OpenGL 2.1 for Windows XP

256MB 3D accelerated video with DirectX 9.0EX with Aero and OpenGL 2.1 for Windows Vista, Windows 7, and Windows 8

To use the GL_EXT_texture_compression_s3tc and GL_S3_s3tc Open Graphics Library (OpenGL) extensions in a Windows XP or Windows 7 guest operating system, you must install Microsoft DirectX End-User Runtime in the guest operating system. OpenGL is an application program interface that is used to define 2D and 3D computer graphics. You can download Microsoft DirectX End-User Runtime from the Microsoft Download Center Web site.
