Created from <SR 3-11494882861>

Information in this document applies to any platform.

Symptoms

Cannot connect to ODA Guest VM through VNC on the port from dom0.

Cause

xm list -l|grep location
(location 127.0.0.1:5901)
(location 2)
(location 0.0.0.0:5900)
(location 18)

-- the related VM is only listening on the local host: 127.0.0.1:5901 and will refuse all the access requests from other clients.

Solution

On Dom0, edit the VM's vm.cfg file by adding line "vnclisten=0.0.0.0" - this will allow connection from any client:

Before: "vfb = ['type=vnc']"

After: "vfb = ['type=vnc,vncunused=1,vnclisten=0.0.0.0']"

Then restart the VM to have the change take effect.
