[libvirt-users] libvirtError: Unable to add bridge br0 port vnet0: Operation not supported

[Maciej Gałkiewicz]

Hi

I am using Libvirt 1.1.2 with Openstack Havana (RC2, nova-network) and
openvswitch 1.4.2+git20120612-9.1. Libvirt vif driver (
nova.virt.libvirt.vif.LibvirtGenericVIFDriver) generates config likes this:

    <interface type='bridge'>
      <mac address='fa:16:3e:44:30:a4'/>
      <source bridge='br0'/>
      <model type='virtio'/>
      <filterref filter='nova-instance-instance-000003d8-fa163e0b07a7'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x03'
function='0x0'/>
    </interface>

and instance fails to start with:

2013-10-16 11:16:13.004+0000: 11943: info : virNetDevProbeVnetHdr:122 :
Enabling IFF_VNET_HDR
2013-10-16 11:16:13.105+0000: 11943: error : virNetDevBridgeAddPort:370 :
Unable to add bridge br0 port vnet0: Operation not supported

If I add <virtualport type='openvswitch' /> inside <interface
type='bridge'>...</interface> it seems to work fine. Is it nova-network or
libvirt bug or some misconfiguration?

regards
