Egress queuing is possible (and is the most common use case when
applied to a physical interface) - look at the QoS section of the
ovs-vsctl man page.  However, it's unlikely to be particularly useful
when applied to VMs.  It won't reduce link usage at all because the
traffic has already arrived and it's unlikely to reduce CPU usage very
much single QoS is expensive to perform.
