[libvirt] 802.1q vlan-tagging support for libvirt

Are there any plans to support configuring 802.1q VLAN tagging through libvirt? 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? Thanks, -Klaus -- Klaus Heinrich Kiwi <klausk@linux.vnet.ibm.com> Linux Security Development, IBM Linux Technology Center
