I've reviewed all the submissions James has posted for comments so
far, and am pretty happy with the way it now integrates with libvirt.

If yourself & James are happy with what they're doing from a SELinux /
security model point of view, then there's no reason they shouldn't
be posted for final merge now.

The latest patches I've seen from James were fine by me. If you've
got proof of concept for the disk label stuff, then by all means
post it now for early review, even if its not developed far enough
for use yet.

How to tell virt-manager what the available / acceptable labels are is
an interesting problem I don't think we've considered yet. We could
provide metadata in the host capabilities XML format (virsh capabilities)
Or add a new  security capabilities XML doc with info. Or as a first
cut just hardcode them in virt-manager,  and assume everyone's using
the SELINux reference policy to start with, and consider customization
as a v2 thing.
