Xen users - Oct 2011 - Automatic vncviewer startup

Hello,

is there a way to start automatically the vncviewer when a domU starts?
When I was using the xm toolstack I could use "xm create domain.cfg
-vncviewer"
or something similar (if I''m not wrong), but I don''t know how
to do it with the
xl toolstack. At the moment, I have to create the domain using
xl create domU.cfg, then xl list to see the domU id and then xl
vncviewer <domU_id>
to start vncviewer.

Is it possible?

By the way: does the analogue of ''xm new domU.cfg'' exist in
the new xl
toolstack?

OK, meanwhile I''ve found a workaround for this, using a combination of
the
xl commands:
xl create domU.cfg && xl vncviewer `xl domid domU_name`
but the question is still valid.

But I didn''t find an answer yet for this.

As far as I can see not in this case. It says: option `'' not supported.
Also ''xl new'' doesn''t exist.

Hi Flavio,

You could wrap the commands in a shell script (make it executable):

     #!/bin/bash

     xl create vm14.cfg
     xl vncviewer vm14 &

Personally, I prefer that the domU run its own vncserver.  That way I 
can configure it to use the whole screen and then resize it as I see fit 
using regular window controls.  But then again, I have to start the 
viewer manually (alt-f2, then vncviewer domU-hostname:1).

Take a look at tigervnc.

xl create vm.cfg

And this is actually what I''ve done at the end.
It seems there is no alternative solution to this problem.

I know the create command but xm new is different.
when the old xm toolstack was used, "xm new" was for adding
the domU to the xend manager (so, even if the domUs were not
running, if you execute xm list, you were able to see the domains
anyway) and then you could do "xm start domainname" to start the domU.

In this case, xend is no longer present, so as far as I understand, this
"trick" cannot be done anymore. Am I correct?
Did I explain myself correctly? (maybe I didn''t write very well what I
mean,
let me know if it is not clear please).

Thanks a lot,
