Remote clients can connect to modular daemons directly as long as
virt-ssh-helper is available on the server side. As a fallback, nc
will be used and the connection will go through virtproxyd.

So yeah, nc will only be used when virtproxyd is involved, and so it
makes sense to move the Recommends to that package instead of
libvirt-daemon-common.


Based on the above, however, I wonder if we should have at least a
weak dependency on libvirt-daemon-proxy for libvirt-daemon-kvm and
friends? As things are right now, clients that are more than ~2 years
old will not be able to connect to the server unless the admin
manually installs libvirt-daemon-proxy. Are we okay with that?
