I've never been particularly concerned about the extra functionality that is
introduced when meta-virt is added, since container support (and arguably
lxc if you are doing "virtualization") is a fairly basic feature.

I'm concerned that within meta-virt we are creating an undocumented set of
DISTRO_FEATURES, and over using the concept. The items are already
controlled via PACKAGECONFIG, so users have flexibility from that point
of view.

We could also use IMAGE_FEATURES as an alternative to distro features,
since we are really only coordinating libvirt and the kernel when "lxc" is a
distro feature .. which arguably isn't distro wide.

Outside of the lxc change, everything looks pretty good, I'm going to ack
the individual patches to make it clear :)

Don't misunderstand my comments, there's no white/black answer here, I'm
just trying to spark a discussion to make sure the direction is clear
and we have
a pseudo-consensus :)

Cheers,

Bruce
