Re: Dashboard VNC Console failed to connect to server

  Thread Previous • Date Previous • • Thread Next 
I've got the same problem.
When I try to connect to the instance using VNC through the dashboard, I've got this error. I then went in /var/log/nova/nova-xvpvncproxy.log and it contains nothing related to any attempt to get connected to any instance. It seems this nova-xvpvncproxy process doesn't notice anything. 


When I try to connect using VNC through virt-manager, it works.

Thanks for the reply.
I've added the flags that you mentioned on my nova.conf file. I'm using a all in one installation, the flags are configured this way. 
--vncserver_listen=127.0.0.1
--vncserver_proxyclient_address=127.0.0.1
--novncproxy_base_url=http://192.168.100.142:6080/vnc_auto.html
The public IP of the machine with the OpenStack installation is 192.168.100.142. I've tried to access via browser the address http://192.168.100.142:6080/vnc_auto.html from another machine, but I got nothing.
I can ping and ssh my instances from the OpenStack machine but can't use VNC tab at dashboard page from another machine. The details and other pages from dashboard are fine. Should I associate a public address for my instances? I'm using just the private address at them (10.0.0.2, 10.0.0.3, ...).
I've restarted all the services and created new instances after changing the nova.conf, but nothing has changed.
The error is a 404 not found. (*Error: *Unable to get VNC console for instance "7376e17b-e329-4b8b-b5fc-076e8a80c058".) 
The log from dashboards page looks like this:
    - Page Not Found (404)
    - Requested method: GET
- Requested URL: *http://192.168.100.142/nova/instances_and_volumes/instances/7376e17b-e329-4b8b-b5fc-076e8a80c058/None*
This is the nova-api.log relative to the VNC atempt: http://pastebin.com/wSuyctrg 

Thanks for your time.
Guilherme Birk.

How are you generating this link: http://192.168.100.142/nova/instances_and_volumes/instances/5307a5c5-249b-4eda-b6e4-5b17d349e8ee/None ?
It looks like if horizon is behaving nicely the link would look like http://192.168.100.142/nova/instances_and_volumes/instances/5307a5c5-249b-4eda-b6e4-5b17d349e8ee/vnc <http://192.168.100.142/nova/instances_and_volumes/instances/5307a5c5-249b-4eda-b6e4-5b17d349e8ee/None> 

Also, could you pastie your nova-api.log somewhere?

    Here is my nova-api.log. Looks like nova is having problems with
    the POST at

    Any suggestions ?

    Hey guys,

    I'm using Dashboard with a nova-compute installed in another
    machine, but when I try access VNC Console I get the error "failed
    to connect to server".

    Here is the log -> http://pastebin.com/5DZMfiNE

    Anyone already saw this trouble?
