[libvirt] Bridged network (shared physical device) and libvirt

Hi, Are there any plans to include possibility to configure bridged networks in libvirt? I see the need to be able to actually be able create vlans on physical devices and the bridge the vlan, which I guess is a very normal case for isolating network traffic between different guests. I would be great if it would be possible to both create vlans on physical devices and then also create bridged network connected to any available network (physical/bonded/vlan) /Henrik
