thanks for your answer.


the option of --vncserver_listen is always 0.0.0.0 during I having any change for other vnc's options in nova.conf 


by the way ,if I set --vncserver_listen to controlnote's IP ,can novnc work fine when instance is in compute-note??


thanks

Subject:  Re: [Openstack] What is the correct config for vnc or novnctosuccessfully enable VNC CONSOLE in a browser?

 
See below:
 

but I get some thing strange for:
if I set 
--vnc_enabled=true

--novncproxy_base_url=http://localhost:6080/vnc_auto.html
 --vncserver_proxyclient_address=localhost

--vncserver_listen=0.0.0.0
in nova.conf that it return 

 Oops! Google Chrome could not connect to localhost:6080 
in dashboard,but work fine when I use command nova get-vnc-console demo novnc  ..It return a url as http://localhost:6080/vnc_auto.html?token=XXXXXXXXXXXXXX..
 then I enter this url in chrome with http://172.18.187.110:6080/vnc_auto.html?token=XXXXXXXXXXXXXX 
 ps:172.18.187.110 is the public ip of my openstack server..
It can return my VM's screen ..
 

however,when I set
 --vnc_enabled=true

--novncproxy_base_url=http://172.18.187.110:6080/vnc_auto.html
 --vncserver_proxyclient_address=172.18.187.110

--vncserver_listen=0.0.0.0



and restart all the services ..
 both dashboard and url from command nova get-vnc-console demo novnc returns server connot connect
 
I am wondering how would localhost and 172.18.187.110 be not the same???
 








If you launched this instance before you specified --vncserver_listen, then the instance's vnc server will bind 127.0.0.1.  Furthermore, this configuration will be baked into the instances libvirt.xml file, so changes to --vncserver_listen in your nova.conf will not have any effect for already existing instances.
 

Did you happen to launch this instance before you set --vncserver_listen to 0.0.0.0?  If so, you may try to launch another instance and see if vnc is working properly.


Just for the record, --vncserver_listen is generally set to the hosts management ip, rather than the public ip or 0.0.0.0, for security reasons.

For anyone else who might be hng the same issue.. These two packages, combined with these options will get novnc working on precise.. 

--vnc_enabled=true
--novncproxy_base_url=http://78.153.XXX.XXX:6080/vnc_auto.html
--vncserver_proxyclient_address=78.153.XXX.XXX
 --vncserver_listen=0.0.0.0




I've intentionally kept the version numbers identical to the packages currently in the precise repo's. This will hopefully let apt "do the right thing" once an official update is released..

The novnc package included in 12.04 is outdated/broken..

I know Chuck is planning to fix it ASAP..

In the meantime, I hacked together a fixed .deb.. I can stick it somewhere for you to download if you like?
 

Thanks,

 Hello ,allI installed Openstack as a all-in-one solution ,I got everything runs correctly ,I can ssh to my VMs etc. But there is a problem here: I can not use the VNC tag in dashboard.
 I have installed the nova-consoleauth and novnc by "apt-get" .but I can not statrt the nova-novncproxy service (by the way ,the nova-vncproxy service always runs OK),
When I use the command root@ubuntu:~# service novnc start
 I got the following with nothing else:
* Starting OpenStack NoVNC proxy nova-novncproxy


It only says "starting",but does not say "started"!


 actually it is not started ,by command service novnc status, it says: * nova-novncproxy is not running.


when I use command nova-novncproxy --flagfile=/etc/nova/nova.conf ,I got the following:
 

WARNING: no 'numpy' module, HyBi protocol support disabled
Traceback (most recent call last):
File "/usr/bin/nova-novncproxy", line 40, in <module>

When I use command nova get-vnc-console testVM novnc

but When pasted the url above into my chrome ,I got the following :

 Oops! Google Chrome could not connect to 192.168.0.202:6080

 Suggestions:
 
Try reloading the page

Search on Google:when I click the "VNC " tag in dashboard ,I got the folloing : 




This webpage is not available
 Google Chrome's connection attempt to 192.168.0.202 was rejected. The website may be down, or your network may not be properly configured.
 
Here are some suggestions:
 
Reload this webpage later.
 
Check your Internet connection. Restart any router, modem, or other network devices you may be using.

Add Google Chrome as a permitted program in your firewall's or antivirus software's settings. If it is already a permitted program, try deleting it from the list of permitted programs and adding it again.
 
If you use a proxy server, check your proxy settings or contact your network administrator to make sure the proxy server is working. If you don't believe you should be using a proxy server, adjust your proxy settings: Go to the wrench menu > Settings > Under the Hood > Change Proxy Settings... and make sure your configuration is set to "no proxy" or "direct."
