- Paravirtualization is a way of running multiple instances of
- Linux on the same machine, under a hypervisor. This option
- changes the kernel so it can modify itself when it is run

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.
