CONFIG_PARAVIRT: Enable paravirtualization code

General informations

The Linux kernel configuration item CONFIG_PARAVIRT has multiple definitions:

found in arch/ia64/Kconfig

The configuration item CONFIG_PARAVIRT:

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.

Paravirtualization support (EXPERIMENTAL) found in arch/i386/Kconfig

The configuration item CONFIG_PARAVIRT:

Help text

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 under a hypervisor, improving performance significantly. However, when run without a hypervisor the kernel is theoretically slower. If in doubt, say N.
