Xen users - Jun 2005 - xf86OpenConsole: Cannot open /dev/tty0 (No such file or directory)

Hi

As per previous post I have managed to create and use domains running
variants of linux at a command level.

However, any Remote Desktop or VNC or ssh -X connection to the domain
seems to fial as X won''t start.

If I try and start the X server from the console via startx I gwet the
following error message :-

"xf86OpenConsole: Cannot open /dev/tty0 (No such file or directory)"

Is this because my domainU is missing some modules ?

I appreciate that domainU should be lighter than domain0 but if within
domian1 I type lsmod I get :-

stewart@localhost log $ lsmod
Module                  Size  Used by



i.e. no modules at all.

Is this the cause of my problem?

Regards


Stewart

You can''t just startx because it''ll look for a graphics card
(which it doesn''t
have).

You could run "vncserver" directly (which will start an X server with
a
virtual displayitself).

To use "ssh -X" you don''t need to startx first.  Just run
"ssh -X" then when
you''re logged in, run "xterm".  If that doesn''t
work, post the error message.

I installed tinyvnc into both the domainU and the domain0. Started
"vncserver :1" in domainU and "vncviewer 10.0.0.2:1" and
that worked.

ssh -X 10.0.0.2 followed by xterm did not work.

Error :-
stewart@localhost stewart $ xterm
xterm Xt error: Can''t open display:
xterm:  DISPLAY is not set

My x11forwarding-enabled SSH-setup sets DISPLAY automagically, so I assume
you don''t have enabled the neccessary options for that?
Check your server or client site /etc/ssh/ssh*_config files for that.
I have enabled x11F in both the server and the client iirc, but I don''t
know exactly which one is neccessary ;-)
