As a matter of fact, this would be a nice feature for many network (and
other) settings. For example, right now if you add a host to the static
host mappings in a network, you must restart that network for it to take
effect. Restarting a network disconnects all the guest interfaces using
that network, and either the guests must be restarted, or at the very
least their interfaces must be manually detached and reattached. In
reality, though all that's needed is to update a text file on disk and
SIGHUP dnsmasq.
