Hi Guys, I've recently submitted a patch to support traffic shaping for a network interface (http://gerrit.ovirt.org/#/c/15445/). This work is needed in order to support http://www.ovirt.org/Features/Network_QoS . Given: 'specParams': {'inbound': {'average': '1000', 'peak': '5000', 'burst': '1024'}, 'outbound': {'average': '128', 'burst': '256'}}} Generated xml is the following one: <bandwidth> <inbound average="1000" burst="1024" peak="5000"/> <outbound average="128" burst="256"/> </bandwidth> As you can see I tried to keep the data structure as flat as possible having the bandwidth element not carrying any useful information. Feedback is highly appreciated. Cheers, Giuseppe.
