[one-users] no vnc proxy running opennebula sunstone

[Hector Sanjuan]

Hello,

the name of some config options have changed since 3.2. The install script  
will not replace the value if it is not in the file.

Apart from that

:vnc_proxy_base_port: 0
:vnc_proxy_support_wss: yes (without providing path to the certs)

does not make much sense.


For the VNC configuration, the UI settings of your file should look like  
in the original config file:

Sunstone:  
http://dev.opennebula.org/projects/opennebula/repository/revisions/one-3.8/entry/src/sunstone/etc/sunstone-server.conf

Self-Service:  
http://dev.opennebula.org/projects/opennebula/repository/revisions/one-3.8/entry/src/cloud/occi/etc/occi-server.conf

Stop sunstone/self-service, check that no websockify python process has  
been left running in the machine.

Once there, run the install_novnc.sh script provided with 3.8. The script  
will download the necessary files and update the configs. You can go back  
to the configs to check it is fine. i.e. sunstone-server.conf here:

:vnc_proxy_port: 29876
:vnc_proxy_path: /srv/cloud/one/share/websockify/websocketproxy.py
:vnc_proxy_support_wss: no
:vnc_proxy_cert:
:vnc_proxy_key:

(Sunstone documentation page has more info of what each of these values  
mean)

Restart Sunstone/Selfservice. It should be able to connect to the VM.  
Otherwise, there is a troubleshooting section at:

  http://opennebula.org/documentation:rel3.8:sunstone#vnc_troubleshooting

You can always get back to the list for further support,

Hector
