Re: [Xen-users] How to create a Persistent VNC connection to a VM?

[Casey DeLorme <cdelorme@xxxxxxxxx>]

From my experiences it has nothing to do with the Server side of the connection.

Gnome VNC Viewer (gvncviewer) and OS X ScreenSharing do not crash on window resize, the built in and xtightvncviewer seem to however.

Also, OS X Screen Sharing (launched from terminal "open vnc://ip:display") requires the server to be up to establish the first connection, but afterwards I can reboot the virtual machine as many times as I want and the VNC Client Window remains open throughout the entire process.

To me this either means many of the VNC Clients lack in functionality, or haven't well documented these features.

I think your best bet would be to write a proxy server that keeps the VNC client's connection open and periodically attempts to reconnect to the VNC server when the server goes down.  The VNC protocol is actually really simple, so you could probably implement one without that much difficulty.

Hopefully this is a very simple thing to answer, BUT I have one computer running Xen 4.2-unstable and once you create a VM using the "xl create" command, it creates that VM as well as opens a new VNC port to it.

I than use TightVNC from a second computer running WInXP to connect to the newly created VM on the server.

Now, my question is that as that VNC connections disconnects a LOT during the process of reboots and doing updates and etc and have to reconnect so often, HOW to or is there a simple way to create a persistent VNC connection to the VM no matter what it is doing as long as you do not run the "xl destroy" command on the server, you will still see the VM Console?

Does such a thing have to do with some setting on the Xen server? or it is something with the TightVNC program running on WinXP that is making it disconnect?
