When you check out a View desktop to run on your local computer, the hardware on the client computer must support both the local system and the virtual machine that now runs on it.

Processor Requirements describes the hardware requirements for various View desktop operating systems.

Processor Requirements

Client Computer Requirement



x86 64-compatible

LAHF/SAHF support in long mode

Number of CPUs

Multiprocessor systems are supported

CPU speed

For a Windows XP local desktop, 1.3GHz or faster; 1.6GHz recommended

For a Windows 7 desktop, 1.3GHz or faster; for Aero effects, 2.0GHz or faster

Intel processors

Pentium 4, Pentium M (with PAE), Core, Core 2, Core i3, Core i5, and Core i7 processors

For Windows 7 Aero: Intel Dual Core

AMD processors

Athlon, Athlon MP, Athlon XP, Athlon 64, Athlon X2, Duron, Opteron, Turion X2, Turion 64, Sempron, Phenom, and Phenom II

The AMD CPU must have segment-limit support in long mode.

For Windows 7 Aero: Althon 4200+ and above

64-bit operating systems on View desktops

Intel Pentium 4 and Core 2, and Core i7 processors with EM64T and Intel Virtualization Technology

The Intel CPU must have VT-x support enabled in the host system BIOS. The BIOS settings that must be enabled for VT-x support vary depending on the system vendor. See the VMware knowledge base article at http://kb.vmware.com/kb/1003944 for information about how to determine if VT-x support is enabled.

Most AMD64 processors (except the earliest revision C Opteron processors)

GPU for Windows 7 Aero

nVidia GeForce 8800GT and above

ATI Radeon HD 2600 and above

Although the operating system on the client computer can be 32-bit or 64-bit, the hardware must be 64-bit compatible and must have the Intel or AMD virtualization assist technologies enabled to run a View desktop with a 64-bit operating system. If these requirements are met, you should be able to run a View desktop with a 64-bit operating system on a client that has either a 32-bit or 64-bit operating system.

If you use a default setup for the operating system in the View desktop, the actual disk space needs are approximately the same as those for installing and running the operating system and applications on a physical computer.

For example, Microsoft recommends 16GB of hard disk space for a machine that runs a 32-bit Windows 7 operating system. If you configure a 16GB virtual hard disk for a 32-bit Windows 7 virtual machine, only the amount of disk space actually used is downloaded when you check out the local desktop. For a desktop that is allocated 16GB, the actual download size might be 7GB.

After the desktop is downloaded, the amount of disk space used can grow to 16GB if you configured a 16GB hard disk. Because a snapshot is taken during replication, an additional equivalent amount of disk space is required. For example, if 7GB of disk space is currently being used for the local desktop, the snapshot consumes an additional 7GB on the client computer.

IDE and SCSI hard drives are supported.

You need enough memory to run the host operating system on the client computer, plus the memory required for the View desktop's operating system and for applications on the client computer and the View desktop. VMware recommends that you have 2GB and above for Windows XP and Windows Vista, and 3GB and above for Windows 7. For more information on memory requirements, see your guest operating system and application documentation.

The total amount of memory you can assign to all virtual machines running on a single computer is limited only by the amount of RAM on the computer. The maximum amount of memory for each View desktop on 64-bit computers it is 32GB.

A 32-bit display adapter is recommended. 3D benchmarks, such as 3DMark '06, might not render correctly or at all when running Windows Vista or Windows 7 virtual machines on some graphics hardware.

View Client with Local Mode supports DirecX9c, which becomes enabled automatically on client systems with capable GPUs. DirecX9c includes 3D capabilities such as Google Earth with 3D building turned on, Windows 7 Aero effects, and some 3D games.

To play video at 720p or higher requires a multiprocessor system.
