[libvirt-users] Hotplug/hotadd functionality of libvirt?

First of all, happy new year!

I am interested in the hot plugging facilities of libvirt, in particular 
in what qemu calls 'hot add' of network interface cards. (And also the 
reverse: hot unplugging/removing of NICs.)

I think I am overlooking something, but so far the best I have been able 
to find is:


and it is not entirely clear to me what the relevant virsh commands are. 
The most obvious choice seems to be the iface-* commands such as


but these seem to be about physical rather than virtual network 
interfaces, and the documentation `needs to be written' anyway, and from 
the copyright notice the manual seems to be somewhat outdated by now.

Can you give me a little help with this? Is such hot plug/add 
functionality supported by libvirt in the first place? Is there some 
kind of overview document about this? What is the most authoritative 
documentation of this functionality? Is there a Java or C API to access 
this functionality?

Thank you for any help you can give me,

Kees van Reeuwijk
