Step 7: The OpenStack Dashboard

Submitted by martin on Fri, 2012-03-23 22:39

We can use Nova to start and stop virtual machines now, but up to this point, we can only do it on the command line. That's not good, because typically, we'll want users without high-level administrator skills to be able to start new VMs. There's a solution for this on the OpenStack ecosystem called Dashboard, codename Horizon. Horizon is OpenStack's main configuration interface. It's django-based.

Let's get going with it:
apt-get install apache2 libapache2-mod-wsgi openstack-dashboard

Note: Make sure to install at least the version 2012.1-0ubuntu6 of the openstack-dashboard package, as it contains some changes important for the dashboard to work properly.

Then, open /etc/openstack-dashboard/local_settings.py in an editor. Go to the line starting with CACHE_BACKEND and make sure it looks like this:

CACHE_BACKEND = 'memcached://127.0.0.1:11211/'

Now restart Apache with

service apache2 restart
After this, point your webbrowser to the Nova machine's IP address and you should see the OpenStack Dashboard login prompt. Login with admin and the password you specified. That's it - you're in!

VNC not working

Submitted by haadee on Fri, 2012-05-11 01:31.

Hi,

When I try to use VNC, it doesn'd work. After a while it says: "Error: Unable to get VNC console for instance "b89ba58f-2dc2-4bcb-a81d-cca8bd71791d"

I did reinstall everything from the beginning, but no luck so far. Has anyone had the same problem?

 

Regards,

HD

I'll update the howto to fix

Submitted by martin on Fri, 2012-05-11 12:25.

I'll update the howto to fix this issue. Meanwhile, here's how you do it: Make sure you've got the "novnc" package installed and make sure that "novnc" is started; also make sure that nova.conf contains these entries: 

--novnc_enabled=true

--novncproxy_base_url=http://10.42.0.6:6080/vnc_auto.html

--vncserver_proxyclient_address=10.42.0.6

--vncserver_listen=10.42.0.6

10.42.0.6 must be replaced with your actual IP, of couse. After doing these changes to nova.conf, restart all nova services and log in into the Dashboard again. VNC should now be working.
