In linux kernel since version 2.6.21 (release Date: 2007-04-25)
VMI provides a paravirtualized interface to the VMware ESX server
(it could be used by other hypervisors in theory too, but is not
at the moment), by linking the kernel to a GPL-ed ROM module
provided by the hypervisor.
As of September 2009, VMware has started a phased retirement
of this feature from VMware's products. Please see
feature-removal-schedule.txt for details. If you are
planning to enable this option, please note that you cannot
live migrate a VMI enabled VM to a future VMware product,
which doesn't support VMI. So if you expect your kernel to
seamlessly migrate to newer VMware products, keep this
disabled.
