You must install Workstation on a host system that meets certain processor requirements.

The host system must have a 64-bit x86 CPU that meets the following requirements.

LAHF/SAHF support in long mode

1.3GHz or faster core speed

Multiprocessor systems are supported.

When you install Workstation, the installer performs checks to make sure the host system has a supported processor. You cannot install Workstation if the host system does not meet the processor requirements.

The operating system that runs inside a virtual machine is called the guest operating system. To run 64-bit guest operating systems, the host system must have one of the following processors.

An AMD CPU that has segment-limit support in long mode

An Intel CPU that has VT-x support

If you have an Intel CPU that has VT-x support, you must verify that VT-x support is 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.

When you install a 64-bit operating system, Workstation performs checks to make sure the host system has a supported processor. You cannot install a 64-bit operating system if the host system does not meet the processor requirements.

To support Windows 7 Aero graphics, the host system should have either an Intel Dual Core 2.2GHz or later CPU or an AMD Athlon 4200+ or later CPU.
