If you can make the change using the virsh command line tool, then you
can make the same change using API (since virsh is just a shell wrapper
around the API).
For a runtime change, maybe you can use virDomainUpdateDeviceFlags() but
I haven't try if it works with <filterref/>.
I see 'virsh nwfilter-edit' as a way to edit a nwfilter definition; but
I'm not familiar enough with nwfilter to know if live edits of the
hcount filterref will affect a live domain definition. It seems like it
should be doable technically, although it may require someone to write a
patch.
