Say Y here to get to see options related to running Linux under
various hypervisors. This option alone does not add any kernel code.

This changes the kernel so it can modify itself when it is run
under a hypervisor, potentially improving performance significantly
over full virtualization. However, when run without a hypervisor
the kernel is theoretically slower and slightly larger.
