Could not load neutron.agent.linux.interface.OVSInterfaceDriver

Hey guys.. can anyone help me out solve this problem??

I am running classic scenario with 3 nodes (controller, network, compute) with OpenvSwitch. All of my agents are alive (neutron agent-list).

If I check nova service-list, they all work like they should. (all enabled, up).

Trouble is when I check neutron-dhcp-agent on the network node, I get following warning

WARNING stevedore.named [-] Could not load neutron.agent.linux.interface.OVSInterfaceDriver

I get the same warning when I check neutron-l3-agent...

When I launch instance I get:

[Error: No valid host was found. There are not enough hosts available.].

In the nova-compute logs I saw:

PortBindingFailed: Binding failed for port 04310927-c1a2-452b-861f-03c296ce5b20, please check neutron logs for more information.

Any idea?
