I'm having a similar issue. I'm following that guide too and got the controller node running on a VM with keystone, glance and nova (minus compute) and all worked fine. However, on the compute node (running on a real server) I can't get the nova-compute service to start at all. It just hangs there with few helpful log messages even with the debug option on.

If you just run it as a service you will notice that it will timeout at about 90 seconds and try to start again and will just stay in that loop. For troubleshooting, I'm trying to start it manually: /usr/bin/nova-compute --debug --config-file /etc/nova/nova.conf --log-file /var/log/nova/nova-compute.log

You say "it won't start anymore". Did you ever get it to start successfully?

I've asked the same question a couple of hours ago, but it's waiting moderation. Hopefully we will have an answer soon.

Update: maybe this helps you.

The issue I was seeing was caused by the /var filesystem dropping below 1GB and rabbitmq blocking publishers. From the rabbitmq logs:

=INFO REPORT==== 12-Nov-2014::15:14:32 ===
Disk free space insufficient. Free bytes:696029184 Limit:1000000000

=WARNING REPORT==== 12-Nov-2014::15:14:32 ===
disk resource limit alarm set on node 'rabbit@cha-ops-xen-v04'.
