Sanity check question:

Why not add the select stuff, i.e. this:

	select NET
	select NETDEVICES
	select PCI
	select BLOCK
	select BLK_DEV
	select NETWORK_FILESYSTEMS
	select INET
	select EXPERIMENTAL
	select TTY
	select SERIAL_8250
	select SERIAL_8250_CONSOLE
	select IP_PNP
	select IP_PNP_DHCP
	select BINFMT_ELF
	select PCI_MSI
	select HAVE_ARCH_KGDB
	select DEBUG_KERNEL
	select KGDB
	select KGDB_SERIAL_CONSOLE
	select VIRTUALIZATION
	select VIRTIO
	select VIRTIO_RING
	select VIRTIO_PCI
	select VIRTIO_BLK
	select VIRTIO_CONSOLE
	select VIRTIO_NET
	select 9P_FS
	select NET_9P
	select NET_9P_VIRTIO

to the option below which we already have. It is in the same sense a KVM
guest support deal.

Hmm.

KVM people, any objections?

config KVM_GUEST
        bool "KVM Guest support (including kvmclock)"
        depends on PARAVIRT
        select PARAVIRT_CLOCK
        default y
        ---help---
          This option enables various optimizations for running under the KVM
          hypervisor. It includes a paravirtualized clock, so that instead
          of relying on a PIT (or probably other) emulation by the
          underlying device model, the host provides the guest with
          timing infrastructure such as time of day, and system time
