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and the documentation `needs to be written' anyway, and from the copyright notice the manual seems to be somewhat outdated by now.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,
I think virsh attach-interface / detach-interface is what you are looking for. Another option is to write a little XML snippet and virsh attach-device it. Michal
