Hi all,

I installed the VNC server in one of the VM created via Ovirt.
Now when I try to take the remote for it, It is showing only a blank black screen.

Could someone help me with this?

Thanks Wesley,

I followed the step: https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-vnc-on-ubuntu-18-04 provided in this link to install tight VNC.
I can see the 5901 port is used for VNC server in my VM

Now As per the link you provided, I tried
ssh -L 5901:127.0.0.1:5901 -C -N -l test 172.1.1.1

Now when I tried with Remmina Desktop client (VNC), It is showing only a blank page. 

Also after this bonding, Do I need to use the IP address as 127.0.0.1 and port as 5901 in guacamole? 

Thanks,
Hari

Whoops, I realize now that you are trying to connect to the oVirt VNC server to see the guest?

So your VM has IP address 172.1.1.1 and it is running a VNC server?  I do not believe this is an oVirt issue, it sounds like a VNC issue.

On the VM hosting the VNC server, try checking Netstat to make sure that VNC is listening.
netstat -tulpn

Once you get the port number, make sure your firewall is allowing the port as well.

You can also setup the VNC configuration in Guacamole's web interface.  I run CoreOS as a guest and I have a guacamole instance setup in docker that I use.

Hi Team,

I have a VM for which I applied the console configuration as VNC.
Now I have installed a tool Guacamole to connect to this VM from outside.
As per Guacamole, It expects the following parameter to connect to the VM using VNC,

<connection name="Unique Name">
    <protocol>vnc</protocol>
    <param name="hostname">172.1.1.1</param>
    <param name="port">5901</param>
</connection>

I understand that the IP Address is VM's IP address but what is the port I need to use for connecting to the VM? What is the  VNC server port in ovirt?

Anyhelp is appreciated. 

Thanks,
Hari
