For networking, the first two items will be available in the next 
release of libvirt.

The last 4 are not. Yet.

Yes, the discussion you point to petered out due to everybody being 
pre-occupied (it may have continued longer on the netcf mailing list), 
but it's definitely intended to go in. If I recall correctly, the plan 
is to add that functionality to netcf, then publish it via libvirt's 
RPC. lutter - am I remembering correctly?
