[libvirt] 802.1q vlan-tagging support for libvirt

Are there any plans to support configuring 802.1q VLAN tagging through

My understanding is that libvirt would use vconfig to create tagged
interfaces, while using a physical interface as trunk (e.g., eth0 is the
trunk, eth0.20 the interface with the '20' vlan tag).

Then it would add the tagged interface (eth0.20) to a bridge with the
guest virtual interface.

I don't know how libvirt would need to be extended to be able to
properly 'manage' those 802.1q-enabled virtual switches. Another
question would be how libvirt-CIM would support this.

Is anyone interested/working on this?
