ovs : tunnel_type not in the tunnel_sync RPC answer

[Mathieu Rohon]

since https://review.openstack.org/#/c/33107/21 has been merged, the agent waits for tunnel_type is the tunnel_sync rpc answer, but the ovs plugin doesn't provide this information

Mathieu, is this only a problem with the ML2 TypeDriver patches? Because the review you're mentioning here worked just fine every time I functionally tested it. Are you perhaps not setting up your devstack correctly? With this review [1], you have to set up devstack as follows:

Control:
Q_AGENT_EXTRA_AGENT_OPTS=(tunnel_types=vxlan)
Q_AGENT_EXTRA_OVS_OPTS=(tenant_network_type=vxlan)
Q_SRV_EXTRA_OPTS=(tenant_network_type=vxlan tunnel_type=vxlan)

Compute:
Q_AGENT_EXTRA_AGENT_OPTS=(tunnel_types=vxlan)
Q_AGENT_EXTRA_OVS_OPTS=(tenant_network_type=vxlan)

Give that a try and see if it helps. This may only be an issue when running with ML2.

I use the Openvswitch agent with only :
ENABLE_TENANT_TUNNELS=True
in my localrc

the logs I provided have been resolved by the bug :
https://review.openstack.org/#/c/37020/

the real logs that this issue provides comes from an agent on a second compute node :

    Add gre tunneling support for the ML2 plugin

    This patch add the type_driver GRE to enable the creation of GRE
    tunnels with the OVS agent.
    No Endpoints ID are managed. Only Endpoint IP are stored in DB,
    and this IP is proposed as an endpoint ID for the OVS agent.
    It also fixes the bug 1201471.
