| 141 | Virtual Machine Extensions are provided in many x86 CPUs. These |
| 142 | provide various facilities for allowing a host OS to provide an |
| 143 | environment where potentially several guest OSes have only |
| 144 | limited access to the underlying hardware. This is achieved |
| 145 | without resorting to software trapping and/or instruction set |
| 146 | emulation (which would be very slow). |
| 147 | |
| 148 | Intel's implementation of this is called VT-x. This option enables |
| 149 | VT-x this so that the OS that is booted by U-Boot can make use of |
| 150 | these facilities. If this option is not enabled, then the host OS |
| 151 | will be unable to support virtualisation, or it will run very |
| 152 | slowly. |
