One more thing. Would it be possible to also implement new APIs to manage network bandwidth on-the-fly? It's not for this patchset but is does sound like a good idea to have the possibility to, for example, restrict bandwidth of a running domain since more domains need to use the network or increase the bandwidth because host's owner got more money from domain's owner :-) Jirka -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
