Hi guys,
I've just installed OpenNebula 3.6 on a computer running CentOS 6.2
acting as a frontend. Also, I have 2 additional computers running CentOS
6.2 acting as a host with qemu-kvm installed. Sunstone is properly working.
The problem is that after configuring a template for a new VM, when I
create the VM, the status appears to be RUNNING but I can't connect via
VNC to the VM.
In the template I've configured:
GRAPHICS=[
LISTEN="0.0.0.0",
TYPE="vnc" ]
I've tried to follow the vnc_troubleshooting guide for solving this
issue, but I guess I've missed something important. These are the results:
I think novnc is properly installed and sunstone-server.conf contains
the right websockify path.
It's installed python 2.6.
When I try to launch VNC via sunstone web it appears another window with
this output: "Failed to connect to server (code: 1006)", so I have no
other choice than closing it.
Examining sunstone-server.log, this is the relevant output for the
previous action:
Tue Aug 21 14:25:59 2012 [I]: Starting vnc proxy:

"POST /vm/5/stopvnc HTTP/1.1" 200 - 0.0623
Once I've checked that no websockify was running on the server and port
35781 was unused, I've manually launched novnc on the frontend executing
"/usr/share/one/noVNC/utils/websockify -v 35781 Host1:5905"
This is the output:
WARNING: no 'numpy' module, HyBi protocol is slower or disabled
WebSocket server settings:
- Listen on :35781
- Flash security policy server
- No SSL/TLS support (no cert file)
- proxying from :35781 to Host1:5905
Then, I try to establish a VNC connection from my PC using a VNC client
(vinagre) against the frontend specifying the listening port (35781). It
appears to connect, but a few seconds later it disconnects. This is the
output from the frontend (novnc manually launched):
1: 192.168.101.119: new handler Process
1: 192.168.101.119: ignoring socket not ready
I've tried the same from the frontend itself (against the localhost).
This is the output:
2: 127.0.0.1: new handler Process
2: 127.0.0.1: ignoring socket not ready
The same test but using Firefox from my computer:
3: 192.168.101.119: Normal web request received but disallowed
Finally, with novnc manually launched and listening on the frontend, I
tried to connect via VNC to the VM, using sunstone web GUI. It appeared
the same window stating "Failed to connect to server (code: 1006)".
Also, this is the output on the command line:
4: 192.168.101.119: new handler Process
4: 192.168.101.119: Plain non-SSL (ws://) WebSocket connection

4: connecting to: Host1:5905
4: handler exception: [Errno 113] No route to host
4: Traceback (most recent call last):
File "/usr/share/one/noVNC/utils/websocket.py", line 767, in

error: [Errno 113] No route to host
I can connect via ssh from the frontend to both hosts (host1 and host2)
without having to introduce password. Hostnames are properly resolved to
IP addresses.
Please, could anybody help me with this issue?
Thanks in advance.
Carlos.
