Hi Thomas,


Thanks for your advice.


There is no graphic running on the server which is headless.  I
configure the server remotely via ssh connection on a workstation.


Please explain in more detail.  The CD running on /dev/scd0 is an
installer to install Ubuntu 6.06 NOT an ISO image.


TIA

so if you want to access the "vga monitor" of the virtual machine, you 
have to add "-vnc :0" and then connect with a vnc to "physical-host-ip-or-
dnsname:0"

Hi Thomas,


Thanks for your advice and URL.


Performed following test but failed.


# kvm -hda ubuntu6.06.img -cdrom /dev/scd0 -m 512 -boot d -vnc IP:0
Could not parse VNC address

# kvm -hda ubuntu6.06.img -cdrom /dev/scd0 -m 512 -boot d -vnc IP:1
Could not parse VNC address


# dpkg -l | grep vnc
No printout


I suppose VNC not installed.  Which of the following packages need to
install?
vnc4server 
linuxvnc 
python-gtk-vnc


TIA

You should run it as:
# kvm -hda ubuntu6.06.img -cdrom /dev/scd0 -m 512 -boot d -vnc :0

qemu contains a built in vnc-server. Thomas meant that you should then
connect with a vncviewer to this machines ip:0.

Tried it just hangs there.  I don't run X on the server.

I can connect the server with SSH on desktop.  I doubt whether I have
VNC-client running on desktop

# dpkg -l | grep vnc
No printout

Then it is working, since you are running it with -vnc :0 kvm/qemu
will provide all the output to the vnc console. so this is a sign that
it is working.
By now performing netstat -antp you should see that the qemu process
is listening on port 5900 which is the vnc-port.

You will have to install a vnc-client on your desktop (not on the
image that you are trying to run, on the desktop that you are writing
on right now!). If you install it on the same machine that you run
qemu/kvm on then simply put 127.0.0.1 as the remote server.

on kvm-machine) kvm -hda ubuntu6.06.img -cdrom /dev/scd0 -m 512 -boot d \
-vnc :1

on another host with) vncviewer kvm-machine:1

On the local desktop after ssh-connect the server running;

# netstat -antp
Active Internet connections (servers and established)

Is it 5901 the vnc-port?

Could you please explain in more detail.  Thanks


Can I install vnc-client on the server and run it on the desktop
remotely?  Similar to X forwarding.  If YES please advise how to
achieve it.  TIA
