	  Lguest is a tiny in-kernel hypervisor.  Selecting this will
	  allow your kernel to boot under lguest.  This option will increase
	  your kernel size by about 6k.  If in doubt, say N.

	  If you say Y here, make sure you say Y (or M) to the virtio block
	  and net drivers which lguest needs.
Move lguest guest support to arch/x86. Lguest has two sides: host support (to launch guests) and guest support (replacement boot path and paravirt_ops). This moves the guest side to arch/x86/lguest where it's closer to related code.

x86: Make Linux guest support optional Put all config options needed to run Linux as a guest behind a CONFIG_HYPERVISOR_GUEST menu so that they don't get built-in by default but be selectable by the user. Also, make all units which depend on x86_hyper, depend on this new symbol so that compilation doesn't fail when CONFIG_HYPERVISOR_GUEST is disabled but those units assume its presence. Sort options in the new HYPERVISOR_GUEST menu, adapt config text and drop redundant select.

lguest: select CONFIG_TTY to build properly.

LGUEST_GUEST: fix unmet direct dependencies (VIRTUALIZATION && VIRTIO) Honor the kconfig menu hierarchy to remove kconfig dependency warnings: VIRTIO and VIRTIO_RING are subordinate to VIRTUALIZATION. warning: (LGUEST_GUEST) selects VIRTIO which has unmet direct dependencies (VIRTUALIZATION) warning: (LGUEST_GUEST && VIRTIO_PCI && VIRTIO_BALLOON) selects VIRTIO_RING which has unmet direct dependencies (VIRTUALIZATION && VIRTIO) Reported-by: Toralf F_rster <toralf.foerster@gmx.de> Signed-off-by: Randy Dunlap <randy.dunlap@oracle.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> 2011-01-02 02:08:46 +07:00			`select VIRTUALIZATION`
Lguest support for Virtio This makes lguest able to use the virtio devices. We change the device descriptor page from a simple array to a variable length "type, config_len, status, config data..." format, and implement virtio_config_ops to read from that config data. We use the virtio ring implementation for an efficient Guest <-> Host virtqueue mechanism, and the new LHCALL_NOTIFY hypercall to kick the host when it changes. We also use LHCALL_NOTIFY on kernel addresses for very very early console output. We could have another hypercall, but this hack works quite well.
