Hi all,
This is my first post here although I admit I did post this same
question on Linuxquestions.org with no success. I hope you can help me
solve this as I am unable to create any VMs anymore.
I have a KVM server and am trying to add a new VM. The problem is I am
unable to connect to the consle to finish the installation. Could
someone help me please?
I have put the details of the steps I took and my ssh config file for
clarity. It seems I have a problem with a vnc 'security type'.
Any help would be apreciated!

I can see the new VM but when I chose to open the console, the password
is asked again and again without a successful connection to the console.
The following is what I found in the log.

I then tried to make an ssh tunnel and use vncviewer to connect:
$ ssh -p 2200 r...@phoenix -N -T -L 5902:localhost:5902
$ vncviewer localhost:2
Connected to RFB server, using protocol version 3.8
Server did not offer supported security type

That's it. I'm out of ideas. If you do know of a way to install a
debian box without the need for vnc I'm all ears! :)
Hmm, not really sure, haven't seen that 'security type' error before.
Maybe try connecting to the remote VNC using virt-viewer?
virt-viewer --connect qemu+ssh://r...@phoenix:2200/system $vmname

Hi,
Thanks for your answer but virt-viewer reacts the same way. If I use
the line you mention I get asked for a password again and again.
I get the following in the system logs though:
==> /var/log/auth.log <==
Jun 22 21:35:06 phoenix sshd[23876]: Accepted password for root from
x.x.x.x port 55720 ssh2
Jun 22 21:35:06 phoenix sshd[23876]: pam_unix(sshd:session): session
opened for user root by (uid=0)
Jun 22 21:35:07 phoenix sshd[23876]: Received disconnect from x.x.x.x:
11: disconnected by user
Jun 22 21:35:07 phoenix sshd[23876]: pam_unix(sshd:session): session
closed for user root
Would you know of a way to get a running debian OS without the use of a
console?
Many thanks for your help!
