0007460: libvirt is unable to parse bridged & vlan tagged & bonding interface, receiving 'vlan interface misses the tag attribute'

Centos 7 KVM hypervisor with libvirt management library. Libvirt is throwing following error through virt-manager when entering clicking on one of the interfaces in 'Network interfaces' tab of virt-manager: "Error selecting interface: XML Error: vlan interface misses the tag attribute". There are 3 bridge interfaces configured on the host (each for a different vlan) on top of a single bonding interface, working properly. # rpm -qa |egrep 'libvirt|qemu|kvm' libvirt-daemon-driver-nodedev-1.1.1-29.el7_0.1.x86_64 libvirt-daemon-driver-nwfilter-1.1.1-29.el7_0.1.x86_64 libvirt-glib-0.1.7-3.el7.x86_64 libvirt-daemon-driver-network-1.1.1-29.el7_0.1.x86_64 qemu-img-1.5.3-60.el7_0.5.x86_64 libvirt-client-1.1.1-29.el7_0.1.x86_64 libvirt-daemon-config-network-1.1.1-29.el7_0.1.x86_64 libvirt-daemon-driver-secret-1.1.1-29.el7_0.1.x86_64 libvirt-daemon-driver-lxc-1.1.1-29.el7_0.1.x86_64 qemu-kvm-1.5.3-60.el7_0.5.x86_64 ipxe-roms-qemu-20130517-5.gitc4bce43.el7.noarch libvirt-daemon-1.1.1-29.el7_0.1.x86_64 libvirt-daemon-driver-interface-1.1.1-29.el7_0.1.x86_64 libvirt-python-1.1.1-29.el7_0.1.x86_64 libvirt-daemon-driver-qemu-1.1.1-29.el7_0.1.x86_64 qemu-kvm-common-1.5.3-60.el7_0.5.x86_64 qemu-kvm-tools-1.5.3-60.el7_0.5.x86_64 libvirt-daemon-config-nwfilter-1.1.1-29.el7_0.1.x86_64 libvirt-daemon-driver-storage-1.1.1-29.el7_0.1.x86_64 libvirt-1.1.1-29.el7_0.1.x86_64 virt-manager-0.10.0-20.el7.noarch virt-manager-common-0.10.0-20.el7.noarch #
