Re: [Openstack] Nova-compute doesn't start on reboot, only manually

Mon, 28 May 2012 14:36:32 -0700

The line before is

Connected to AMQP server on 10.8.0.1:5672

so i think rabbitmq is already started isn't it?

Best Regards

Hi Stephen
looks like the amqp server doesn't start.
make sure it starts along with the nova-scheduler first.
Does both services start on boot ?

Any idea?

Both of these are MQ timeouts.  You'll want to arrange for your MQ
server to be running when nova starts up.  How you do that depends on
your local architecture.
