vnc problem no connection possible

[Cinux]

Hi all,

i try to get vnc access to a VM which is virtualized with KVM.
To realise this i found this page:
http://pve.proxmox.com/wiki/Vnc_2.0

But if i enable the VNC 2.0 nothing happen.

I have edit the /etc/pve/local/qemu-server/101.conf

and add following:

args: -vnc 0.0.0.0:1

At last i have powered off and powered on the virtual machine activate the changes.

If i try to connect to the proxmox machine at port 5901

# telnet 192.168.178.110 5901
Trying 192.168.178.110...
telnet: Unable to connect to remote host: Connection refused

Can somebody help me to clarify what the problem is?

That what i want is to get the same VNC connection like the webinterface of proxmox. But with an external VNC viewer like tigervnc viewer.

Thanks for the help.
