2014-11-22 01:54:36 -0600 marked best answer glance requests: 404 Not Found

I am following this guide, and have trouble doing anything with glance. I first stumpled across this when I tried to add an image like this:

[root@cloud ~]# glance -d image-create --is-public true --disk-format qcow2 --container-format bare --name "Ubuntu" <precise-server-cloudimg-amd64.img 
   HTTP/1.1 404 Not Found

    404 Not Found

    The resource could not be found.

    Request returned failure status.
    404 Not Found
    The resource could not be found.
        (HTTP 404)

Doing an glance image-list gives the same error. In /var/log/glance/api.log, I find

   2013-07-05 17:27:46.613 1653 DEBUG glance.api.middleware.version_negotiation [-] Determining version of request: POST //v1/images Accept:  process_request /usr/lib/python2.7/site-packages/glance/api/middleware/

While doing the image-create command, I can see in top that glance is working for a while, being at the top of the process list. So it seems that glance is connecting and working, but then somehow fails.

On a sidenote, not sure if thats related: when stopping the glance daemons, I get

I had a look at the code, and its the os.killpg(pgid, signal.SIGTERM that causes this, but nonetheless, the daemon is stopped.

2014-01-23 18:42:55 -0600 marked best answer glance Authorization Failed with Errno 104

I am following this guide and have configured everything like in the guide. When I try something like glance image-list, I get

Authorization Failed: [Errno 104] Connection reset by peer

As I am new to openstack, I am not quite sure how to debug this. Whom is glance connecting to, keystone, or the mysql database? If its keystone, how can I check which credentials glance is using (I guess the ones provided in /etc/glance/glance-api.conf and /etc/glance/glance-registry.conf ?) How can I check the credentials with the verifyer directly? ... any hints would be appreciated.

I also found:

# keystone user-list
WARNING: Bypassing authentication using a token & endpoint (authentication credentials are being ignored).
[Errno 104] Connection reset by peer

Maybe there is a connection to the glance authorization error?

2013-08-20 08:13:22 -0600 asked a question horizon not displaying console

Using grizzly on centos 6.4, I have this strange thing with horizon: when I try to view the console of an instance (novncproxy), all I get is

Instance Console

If console is not responding to keyboard input: click the grey status bar below. Click here to show only console

And then nothing. I can "Click here", which gets me a new browser window, with the message

Server disconnected (code: 1006)

and a greyed out Send CtrlAltDel button. Now when I reload this window (typing Ctrl+Shift+r in firefox), I get a functioning console.

When I do this with chrome, I get the console window within horizon, but still "Failed to connect to server (code: 1006)". Then I do the "click here" thingy, a new browser tab opens, and the console is working.

So while I have the basic functionality, I would greatly apreciate to have the console wokring _inside_ horizon _without_ the need to reload. Any hints? Anything I could debug?

2013-08-20 07:57:17 -0600 answered a question nova-novncproxy not connecting to instance

So it turns out this issue is related to myself sitting in an office with a webproxy. I have firefox configured to automatic detect proxy setting for the network. In general it works fine, I can connect to outside websites AND openstack horizon. horizon itself works fine, but it does not show the console window. I can load the console in an extra window, still no conncetion. But if I disable webproxy alltogether, and then reload the window with the console, it works.

So its kind of solved, but I would really like to know why this works like this. I will make a sperate question.

2013-08-08 04:36:27 -0600 asked a question nova-novncproxy not connecting to instance

Following up on my earlier question: I have openstack grizzly on centos 6.4. Things are working, except for console connection to the instances. Instances are up and running, and I can connect to their console with a vnc viewer, e.g. remmina. But I can not connect to their console via novnc. All it gives me is a "Server disconnected (code: 1006)".

hosts involved: haproxy all nova services except nova-compute nova-compute

From an experimental devstack install, I can see that novncproxy is connecting directly to the vnc port of the instance. With this system, this is not the case, novnc is not attempting to connect to the instances console, as I can see from an empty tcpdump on the compute host:

tcpdump -i br-admin-222 port 5907
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on br-admin-222, link-type EN10MB (Ethernet), capture size 65535 bytes

I am sure its the right port, because I can connect to that port with remmina and see the console. Also, I can connect to that port with telnet from the host running nova-novncproxy:

$ telnet 5907
Connected to
Escape character is '^]'.
RFB 003.008

So its not a networking issue.

nova.conf on nova-novncproxy host is


nova.conf on nova-compute host is


If someone could answer any of the following questions, I would be greatfull:

  • how does nova-novncproxy know about which host and which port to connect to for a certain instance? Where is this stored, and how does that information get to novnc?
  • I have started nova-novncproxy in the foreground to get more info with --debug and --verbose, but won't get any errors or warnings. How can I get more info on where exactly this is failing?
  • Any other hints on how to debug this?

nova-compute and nova-scheduler keep going into "down" state. After disabeling and enabeling them, they are listed as up for a short period of time (looks like on refresh cycle), but then stay down, and I don't have access to my instances any more.

2013-08-07 07:40:25 -0600 edited question novnc: Server disconnected (code: 1006)

Using openstack grizzly on centos 6.4, I have a strange problem with console connections to the clients. I am using novnc to view clients console. It has been working, but just recently stopped. The only message I get is "Server disconnected (code: 1006)" on the console window.

The configuration is


but since it has worked before, I don't think its related to this config.

In the compute log I find lots of ERRORS like

compute.log:2013-08-06 10:46:12.051 41171 ERROR nova.compute.manager [-] Instance 38c8c8bd-bf42-f7c2-7371-99c2b80c61a8 found in the hypervisor, but not in the database

but non of the instances I am using shows up, so I am guessing this is unrelated (see this question)

For debugging purposes, I startet nova-novncproxy by hand with the following command:

python /usr/bin/nova-novncproxy --verbose --debug  --web /usr/share/novnc/

After loading the console page, I see
