I feel I should clarify some things here. CONFIG_LGUEST enables a
paravirt hypervisor in the linux kernel, which is completely unrelated
to kvm. virtio (some of the paravirt stuff that kvm guests can make use
of) has close connections to lguest, but the lguest hypervisor is not
needed for anything that involves kvm.
