Well, this means that 'ovsbr0' doesn't exist. Is that so? Can you
share your <interface/> configuration and the network XML?
Michal
so if your libvirt's net is like this:
<network>
<name>ovs-br0</name>
<uuid>e5129e76-1576-4866-97e1-42f14263cfc2</uuid>
<forward mode='bridge'/>
<bridge name='ovsbr0'/>
<virtualport type='openvswitch'/>
....
then you need extra(extra for ovs tools create both for us at bridge
creation time and nmcli(you) need to create those explicitly) port+iface
so this:
$ ovs-vsctl show
output will contain this:
...
Port "ovsbr0"
Interface "ovsbr0"
type: internal
...
