It depends on the threats you are attempting to protect against.
For the sVirt work we're primarily interested in protecting the
network & host from guests, and guests from each other. libvirtd
is the control plane, so it has no choice but to deal with labelling

If on the other hand we were trying to protect against flaws in 
libvirtd itself, then this wouldn't be a viable approach.
