Why not just use -vnc :0 or -curses ?

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

Unfortnately I don't have vncviewer running on the local desktop.  What
can I do?  TIA

it's not a hang.  it's running, but all feedback goes to the VNC port.  maybe 
you'd like it to run in the background, so you get the prompt back.  just add 
a '&' at the end:

yes, and port 5901 is VNC's port 1  (since you used -vnc :1)

you do need a VNC client.  it would be the 'screen and keyboard' of the 
virtual machine.  you need at least that to install an OS.  after that, you 
could setup any kind of network access you like directly to the VM (ssh, X, 
RDP, etc)

I ran Knoppix 5.1 on a PC using tightvnc viewer to install the OS,
Ubuntu6.06 as guest.  It is working now.  I also ran update and upgrade
afterwards.


However I haven't figured out how to start it on next boot.  Do I need
putting the installer on CDRom?  On next boot what command shall I run
to start KVM.  What command shall I run to start the guest.  How to
resize the vncviewer window?  TIA

Please explain in more detail.  ssh is running on the host.  Thanks

Hi Thomas,

I got it by running Knoppix 5.1-1 LiveCD which has vncviewer installed.


On local desktop;

$ vncviewer 192.168.0.110:1
Connected to RFB server, using protocol version 3.7

  Least significant byte first in each pixel.
  True colour: max red 31 green 63 blue 31, shift red 11 green 5 blue 0

ShmCleanup called


The installation window started.  I think I can proceed installing the
guest OS?  However I stopped here because I can bring the mouse in
action over the said window.  Nor the keyboard did function well.  How
to improve them?  TIA


Another question;

If I need to do all steps remotely on local desktop I need to start 2
Xterms to ssh connect the server.  


One to run the command;
# kvm -hda ubuntu6.06.img -cdrom /dev/scd0 -m 512 -boot d -vnc :1

it will hang after executing the command


Another Xterm to run;
# vncview 192.168.0.110:1


Is there a clue?  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

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.

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
