[XEN - dom0] Ubuntu 12.04.5 server x64bit , using it on CLI Mode - no GUI installed

[domU - guest] HVM guest created via configuration file, I Determine the started DomU port attached with :

# xm list --long | grep location

but when i try to connect to guest with vinagre after exporting $DISPLAY to 127.0.0.1:5900 (since I am using Ubuntu ) I get the error-warning [Gtk-WARNING **: cannot open display] :

:~$ sudo vinagre 127.0.0.1:5900
:~$ (vinagre:process_number) : Gtk-WARNING **: cannot open display

If i type (found it on google):

:~$ sudo vinagre 127.0.0.1:5900 >/dev/null 2>&1 &1 
I get this >>> : [1]<process_number>

and then nothing happens..

If I try to connect to domU via console (sudo xm console ) System stucks and I can't type or do something just reset via desktop button

Please ask me if you need further information about the problem .. Thanks in advance

Your question provides the answer - "no GUI installed". If there's no GUI installed (no X libraries), then there's no display for graphical programs to connect to.

  • So how am I supposed to install the guest HVM operating system and connect to it ?.. since xm console crashes ? I chose not to install GUI package on main server because Nvidia drivers(I use nouveau drivers instead) + XEN don't work well and system doesn't boot at all / freezes / gets blackscreens.. – User1911 Apr 20 '15 at 20:31
  • You need a graphical display somewhere. It doesn't have to be on your hypervisor - you can SSH in to your hypervisor from another machine that does have an X server installed and simply forward X (for Red Hat and Fedora type Linuxes, use ssh -Y to accomplish this). – John Apr 21 '15 at 21:03
  • I truly love you .... Sorry for the late answer :D I Managed after so long to connect to it .. but when I do i get this error : ** (vinagre:5619): WARNING **: Failed to initialize mDNS browser: Failed to create avahi client: Daemon not running and after installation the guest VM asked me to reboot and it crashed : / I can't do something now, everytime I am trying to connect to it the page is black and grey with cubes all over the place, with GUI not showing up on vinagre ! – User1911 Apr 23 '15 at 22:23
