Description

Hi,
In my template, I have 'GRAPHICS = [type="vnc",listen="0.0.0.0", port="-1", keymap="fr"]' This sets the VNC port to be the first free port above 5900 at the time the VM is launched. I am using KVM.

This config breaks noVNC. (because OpenNebula things the VNC port is VNC_BASE_PORT + vm_port == 4999 bydefault)

I propose the following workaround : if hypervisor is KVM and vnc port is set to -1 then search for the correct VNC port (virsh dumpxml #vmid | grep vnc).

It's low priority and I could live without the noVNC support but if you have a few minutes and the implementation is not too messy, that would be great.

History

#1 Updated by Hector Sanjuan almost 7 years ago

  • Category set to Sunstone

If you want OpenNebula to choose a VNC port for you, you can just avoid specifying PORT in the GRAPHICS section. this will not be the first available port though, but base_port+vmid.

As things are, OpenNebula should know a priori which port VNC has for each VM.

#2 Updated by Ruben S. Montero over 5 years ago

  • Category changed from Sunstone to Core & System

This should be checked by OpenNebula core, so -1 is not allowed in PORT
