Open Stack

Dear all,

I am running openstack grizzly on 2 nodes, with multi-host options and
without conductor.

Node 1 has compute, api, network, etc

Node 2 has compute, network

When launching new instances, those that are launched on the 1st node
launches fine. Those not on node 2 gets stuck in BUILD. "nova show xxx"
prints the following (snipped)

| status                              | BUILD
           |
| updated                             | 2013-04-25T11:37:29Z
            |
| OS-EXT-STS:task_state               | scheduling

I've been reviewing the logs and there are no errors. I have a few
questions and hope someone can help.

1) How do I start tracing this error?

2) In multi-host mode, are the compute nodes supposed to connect to AMQP of
the main node, or themselves? I specified rabbit_host and it still shows
nova-compute connecting to localhost.

3) In scheduler.log, there is the following
2013-04-25 19:37:29.064 WARNING nova.scheduler.host_manager
[req-2272a45e-8e8a-4af0-96cd-b8a387e051fa 91cd099661f54df7bad0c7248c0451ca
c91d0ed52321439c8b7d0c05b89bb0c8] No service for compute ID 2
Is this what is causing the problem?

4) If I were to use conductor in multi-host, do I need a conductor for each
compute node? If not, how do I specify where is the conductor?

Any advice is greatly appreciated.

Thanks,
WP
