VNC Console in OpenStack Dashboard

https://answers.launchpad.net/openstack-dashboard/+question/153427

Thank You. I shall try this and get back to you.

cd ~/src/openstack-dashboard/trunk
bzr merge lp:~sleepsonthefloor/openstack-dashboard/vnc_console

I think we have to install nova-vncproxy and run it up , but I can not find any method to install nova-vncproxy .

I installed nova from trunk PPA , but there's no nova-vncproxy package .

So confusing now.....

OpenStack Cactus release mentions the below point as one of its new features ..

"Thanks to the VNC Proxy, users can now access their instances through a websocket enabled browser (like Google Chrome)"

I assume vncproxy is available by default now. Please correct me if I am wrong.

Also wondering there is not mention about this in cactus docs.

Hi Hugo Kou ,

I have merged dashboard vnc ... Now i get option for vnc in the dashboard. Yet as you said still there is lot of configuration needed.

Also I have been reading this post on the same issue https://answers.launchpad.net/openstack-dashboard/+question/153427

Please let me know if your findings .

Hope the one who has the openstack dashboard screencast with vnc working can help us out to resolve this isssue.

I too shall keep digging more to understand it.

Regards,
Kanthi

dude ~

run up nova-direct-api
run up nova-vncproxy
set flag --vncproxy_url= in nova.conf

and VNC console will l works for you

Hi Hugo,

Can you please brief the above steps and help me understand them. I have currently a working openstack dashboard with vnc merged into it.

When I tried to run nova-vncproxy i have the following error

root@openstack-manual:~/cactus/cactus/bin# ./nova-vncproxy
/usr/lib/pymodules/python2.6/paste/deploy/loadwsgi.py:8: UserWarning: Module nova was already imported from /root/cactus/cactus/nova/__init__.pyc, but /usr/lib/pymodules/python2.6 is being added to sys.path

you need to do what it says in the error and you also need to add the flag:
--vncproxy_url=http://<ip of vnc proxy>:6080

and you should run vncproxy with flagfile as well: ./nova-vncproxy --flagfile=/path/to/flagfile

Thank You Vish and Hugo. I got it now

Since Cactus release, Openstack Dashboard supports VNC without having to merge in the ~sleepsonthefloor/openstack-dashboard/vnc_console branch.

So the steps for those running the Cactus release are:

- get the dashboard (http://docs.openstack.org/cactus/openstack-compute/admin/content/installing-openstack-dashboard.html)
- install the custom noVNC (http://github.com/sleepsonthefloor/noVNC)
- configure "-vncproxy_host" in nova.conf
- and install and run nova-vncproxy as described here
