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
