The following patch: d7aa2dfcb1 renamed the
nvp-qos extension to qos-queue which breaks the integration with nova as
nova checks for the nvp-qos extension to be loaded and now it's called
qos-queue. This patch adds back nvp-qos for trunk chasers and another
patch will migrate nova from nvp-qos to qos-queue.
