udevadm failure when running unit tests

[dkehn]

When running the neutron.tests.unit.openvswitch.test_ovs_tunnel.TunnelTestWithMTU unit test failure occur. The "udevadm settle timeout=10 timeout" see File "/home/dkehn/devl/neutron-new/neutron/plugins/openvswitch/agent/ovs_neutron_agent.py", line 801, in setup_physical_bridges, fails waiting for a bridge that is mock-ed.

    Mock the udevadm in the TunnelTestWithMTU test

    When running the neutron.tests.unit.openvswitch.test_ovs_tunnel.
    TunnelTestWithMTU unit test failure occurs because the udevadm is
    timing out waiting on a mock-ed device.
