RE: [Xen-users] VNC to HVM not starting

["Artur Linhart - Linux communication" <AL.LINUX@xxxxxxxxxxx>]

Hello,

 

            I could not test all the combinations, but I think You are right. And if the vncunused parameter is omitted, then also vncdisplay parameter is ignored even if specified - like already wrote Philippe...

 

                        With regards, Archie

From my experience :

when

vnc=1
vnclisten='IP_of_my_xen_server

vncdisplay=4
vncunused=0

Always allocate the port 5900 (standard VNC) + 4 (vncdisplay) = 5904 for the display. If it is used by soem other application this will just hang.

vnc=1
vnclisten='IP_of_my_xen_server

vncdisplay=4
vncunused=1

allocate the port 5900 (standard VNC) + 4 (vncdisplay) = 5904 for the display if it is free else allocate other free port.

vnc=1
vnclisten='IP_of_my_xen_server

vncunused=1/0

allocate free port.

 

Please correct me if my understanding is wrong.

Thanks,
Trilok

Hello,

        Yes, thank You very much, it is it :-)

        So, for me the following configuration

vnc=1
vnclisten='IP_of_my_xen_server' # Here place IP of the Xen server
vncdisplay=4
vncunused=0

        causes the Xen server listens on the given IP on the port
5900 (standard VNC) + 4 (vncdisplay) = 5904
And I can vonnect to it through the VNC viewer!

:-)

The "display" value seems to be valid at least also for the number 21 and
port 5921 (I do not know if there is some max display number)

Dylan, I propose to place such an example into the FAQ You are creating,
sure, if it is not already there ;-)

        With best regards

Be aware that tere seems to be some precedence in the parameters.
If my memory serves well, you must set vncunused to 0 if you want
vncdisplay to be considered.

/P.
