Subject: Kolab KVM-image

I found out it was time to virtualize my Kolab server. There are many reasons 
for doing it, in my case it was simply to cleanly  separate the host from the 
Debian installation with the Kolab server.

I chose KVM and use it directly from the command line. The image is set up to 
use the virtio drivers so that net has great performance and disk has OK 
performance (using a dedicated fileserver with nfs or samba is probably a good 
idea for high traffic servers).

In any case, the image has worked well for me, so I thought maybe others are 
interested in testing it out. You will find it here:
http://ubuntuone.com/p/Hjm/
I guess making a torrent is more sensible, so feel free to do that if you want 
to.

Install KVM, then you can boot it from the command-line. Give it at least 
750MB memory for smooth operation. Boot it firewalled the first time, and make 
sure you change passwords and users to your choices. Currently both user, 
password and root-password is debian. You will find a text file in the /root 
folder with directions to set it up.

To boot it up firewalled, just maneuver to the folder you downloaded it to and 
run:
$  kvm -m 750 Kolab-2.2.4-Lenny-i386-KVM.img

Once set up you can boot it as a first rate citizen on your net. I have the tap 
interface set up with a bridge on the host (for Debian based host it is 
explained in the text file under /root). Then I simply do
$ sudo kvm -drive file=/path/to/Kolab-2.2.4-Lenny-i386-KVM.im,if=virtio,boot=on 
-net nic,macaddr=00:11:22:33:44:55,model=virtio -net tap -m 768

Now it shows on my net with the mac address 00:11:22:33:44:55. I use that to 
give it a fixed IP on my Lan, then all is left is to forward port 25 from the 
external IP with my domain name to my new virtual machine.

I used the binary Kolab packages for Debian according to the instructions, so 
the binary packages should work without hassle when upgrading. Ssh is 
installed for remote access.

Enjoy,
