You must install Workstation Pro on a host system that meets certain processor requirements.
The host system must have a 64-bit x86 CPU with 1.3 GHz or faster core speed. Multiprocessor systems are supported.
When you install Workstation Pro, the installer performs checks to make sure the host system has a supported processor. You cannot install Workstation Pro if the host system does not meet the processor requirements.
Processor Requirements for 64-Bit Guest Operating Systems
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 Pro 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.
