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

Hello, 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: http://libvirt.org/sources/virshcmdref/html/ 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 http://libvirt.org/sources/virshcmdref/html/sect-iface-define.html 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and the documentation `needs to be written' anyway, and from the copyright notice the manual seems to be somewhat outdated by now.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
