Bug Description
Libvirt network rate limiting configuration data of an ethernet interface are not honored when traffic is carried over that interface of the vm. For example, following configuration data, does not result in tc qdisc setting of the tap device in the host.
<interface type="ethernet">
<mac address=
<model type="virtio"/>
<script path=""/>
<target dev="tapa3a0877
<bandwidth>
<inbound average="800" peak="1000" burst="30"/>
<outbound average="800" peak="1000" burst="30"/>
</bandwidth>
</interface>

The issue is fixed and here's the link to the patch. The root cause of the issue was that libvirt while configure tap device, doesn't apply qdisc settings to it. As a result, network traffic for this tap device is not shaped as per the configuration.
