Hi, I am requesting a little help here, I installed Openstack following the "Three-node architecture" following this http://docs.openstack.org/trunk/install-guide/install/apt/content/ch_preface.html (guide), I am stuck launching the instance (cirrOS test image), where I can't get and error status:

nova show demo-instance1

{"message": "Error during following call to agent: ['ovs-vsctl', '--timeout=120', 'del-port', 'br-int', u'qvo749bf21a-b0']", "code": 500, "created": "2014-05-05T04:51:14Z"}

In the nova-compute.log this lines got my attention:

2014-05-05 00:51:14.042 4000 ERROR glanceclient.common.http [-] Request returned failure status.

2014-05-05 00:51:14.043 4000 ERROR nova.compute.manager [req-d448ac3c-9520-4fde-9f2f-0254b6d48f95 edd9a817c8d4424da4e32d71e59d6187 35ef7ed545114d559ef4da0dbd9f3494] [instance: 9cac4056-3dc8-4641-93 58-920946bd76f3] Instance failed to spawn

Stderr: 'ovs-vsctl: no port named qvo749bf21a-b0\n'

if I do a tcpdump in the controller node I see an http error "401 Unauthorized" for glance:

This server could not verify that you are authorized to access the document you requested. Either you supplied the wrong credentials (e.g., bad password), or your browser does not understand how to supply the credentials required.\n

Complete log here: http://pastebin.com/3Ta1DFWL

I have reviewed this site few times, and the configuration for installation/configuration and I can't get to a solution.

My tree nodes are in Ubuntu 14.04 LTS...

Any help is appreciated.

Thanks in advance.

Do you have any ERROR in your neutron log files? If so, pastebin them.

I don't think is a network error, the ovs-vsctl failed command seems to be that the instance failed to spawn, and after failure it tries to delete a non existent port 'qvo749bf21a-b0' (someone need to elaborate on this).

I think the problem lies here:

nova image-list shows

8d6211ab-a8c8-4d0f-ab8a-2782ec91a114 | cirros-0.3.2-x86_64

But nova-compute complaings:

ImageNotAuthorized: Not authorized for image 8d6211ab-a8c8-4d0f-ab8a-2782ec91a114

what is the output of

glance image-show 8d6211ab-a8c8-4d0f-ab8a-2782ec91a114

I have for all my images :

is_public = True
protected = False
status = active

After a lot of time trying to find the effing problem, I could see that nova-compute didn't send any authentication information to the glance service, after reviewing the configuration the problem was a missing line in nova.conf about the auth_strategy:

auth_strategy = keystone

Thanks to those interested in helping me.
