Issues booting an image
Hi!

I've followed the debian+puppet installation guide [1], and have
gotten quite far. With some tweaks I seem to have a more or less
working setup, but when I'm trying to do the "nova boot" command, it
just hangs (even without the --poll option).

I've tried to look everywhere I could in logs and database locks, but
can't figure it out. I'm new to Openstack so I've probably done
something wrong and/or I'm not looking in the right place.

From [2], and the output below it seems that it's stuck in the very
first step/stage "Compute.api.create_db_entry_for_new_instance".

I'm on #openstack on IRC if discussing online is easier.

Some output:

With good help from #openstack I've figured out that the nova-api
module is trying to send a message to the RabbitMQ but the message is
never received on the MQ. If I look at the MQ's summary page, I can
see that no queue has ever gotten a single message.

This is the only output from nova-api.log:

------------------------------------------

I can send and receive messages through the MQ on some test queues I
made myself.

For the archive, this was because the box running RabbitMQ was on the
low side with disk so it blocked all the connections. Cleaning some
stuff made everything more happy.
