We have problems with oslo.messaging in our tests after restart nodes
Steps:
1. Create next cluster - Ubuntu, Simple, Flat nova-network, Cinder for volumes, Ceph for images, 1 controller, 1 compute, 2 cinder+ceph nodes
2. Deploy cluster
3. Reboot all nodes one by one
4. Open Health Check tab
5. Run tests

Expected - tests passed
Actual - tests on volume and instance creation failed. Lots of errors on compute node in nova logs:
2014-09-15 13:08:11 ERROR

oslo.messaging._drivers.impl_rabbit [req-c4c51ee4-f9b7-4e9e-a949-e694f3b21757 ] AMQP server on 10.108.52.4:5672 is unreachable: [Errno 111] ECONNREFUSED. Trying again in 30 seconds.

And on cinder node in cinder logs
2014-09-15 07:40:19 ERROR
