Re Santanu's post:
Hi there,
Just installed KVM on my server without any xwindows system. Then ssh onto the
server (with X11Forward on) and found virt-manager can't open display when I
issue the command:
<blockquote>
santanu pcge:~$ ssh -X root vmw01
root vmw01's password:

[root vmw01 ~]# virt-manager

</blockquote>
I'm a bit rusty on my X, despite setting my DISPLAY variable I got the same
error, I think my display is firewalled from the server in question.
However, I'm using putty / ssh to acces sthe server, and if I turn on X11
forwarding, my env variable is auto-set to a correct value, and I get the X
output on my PC's xterm display.
