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

Sounds like a host mis-configuration related to kernel bridge support
to me.

Could you tell me what might be mis-configured? I am using kernel 3.10.11,
modules openvswitch, bridge, stp and llc are loaded.

Well if you're trying to use bridged interfaces then make sure you have
the normal bridge modules & tools, and not the openvswitch compatibilty
layer which has caused problems for people in the past IIRC.

Looks like my openvswitch installation does not have bridge compatibility.
I have tried removing modules bridge, stp and llc. What is more
package openvswitch-brcompat is not installed and brctl does not show
openvswitch bridge. It must be something else.
