503 As of September 2009, VMware has started a phased retirement
504 of this feature from VMware's products. Please see
505 feature-removal-schedule.txt for details. If you are
506 planning to enable this option, please note that you cannot
507 live migrate a VMI enabled VM to a future VMware product,
508 which doesn't support VMI. So if you expect your kernel to
509 seamlessly migrate to newer VMware products, keep this
510 disabled.
