Public bug reported:
1. My environment is:
Xenserver 6.5
OpenStack latest master branch
Neutron network with ML2 plugin, OVS driver
2. When I ran
tempest.scenario.test_network_basic_ops.TestNetworkBasicOps.test_network_basic_ops
it will always fail.
It failed at finding the new created instance's port before assign a floating
ip to this port.
Relevant log file of tempest:
tempest.scenario.test_network_basic_ops.TestNetworkBasicOps.test_network_basic_ops[compute,id-f323b3ba-82f8-4db7-8ea6-6a895869ec49,network,smoke]

3. This is a failure that can be reproduced each time as long as we use
xen and neutron.
4. I tried investagating with this problem, it dues to nova/neutron race
condition when booting an instance under xen driver, since xen driver
doesn't handle neutron's "network-vif-plugged" notification event.
