debian

To get the lightscriber dvd/cd writer I recently bought to write labels under amd64 debian linux 4.0 I had to do the following things:

• download the basic lightscriber library from http://www.lightscribe.com/
• download the 4L lightscriber label software from LaCie
• convert both rpms with alien to deb files in a debian 4.0 ia32 schroot
• extract both deb files with dpkg-deb -x / towards the root of your amd64 system
• make sure the ia32 chroot libraries are available in the librarypath for the tool
• run the GUI, as root if you want to burn the label on the CD

Use the gimp to make the labels, there are templates with the correct available together with the LaCie software.

To make it work, set the following xmodmappings:

keycode 174 = XF86AudioLowerVolumekeycode 176 = XF86AudioRaiseVolumekeycode 160 = XF86AudioMutekeycode 162 = XF86AudioPlaykeycode 164 = XF86AudioStopkeycode 144 = XF86AudioPrevkeycode 153 = XF86AudioNextkeycode 236 = XF86Mailkeycode 130 = XF86HomePagekeycode 223 = XF86Sleepkeycode 161 = XF86Calculatorkeycode 230 = XF86Favorites

E.g. add this to a file in your homedir and load it with xmodmap from your .xsession file.

I started by downloading the debian-40r0-i386-CD-1.iso via jigdo.
Then I created a disk image file like this:

qemu-img create vdisk.qcow 1G

Then I boot kvm like this:

kvm -hda vdisk.qcow -cdrom debian-40r0-i386-CD-1.iso -boot d -m 256

(It may be needed to change the permissions of /dev/kvm)

Proceed with installation as a normal debian installation. I only installed the minimum.
The default kvm uses a build-in user space networking. However I’d like to have bridged
networking.
First I create a tap0 device in /etc/network/interfaces:

iface tap0 inet manual        pre-up tunctl -b -u <my_user_name> -t tap0        pre-up ifconfig tap0 up        post-down tunctl -d tap0

Make sure you have tunctl installed, its part of the uml-utilities package.
Replace the <my_user_name> by the user you want to run kvm as.
Normally my network interface is configured via DHCP, soo I want to keep that.
However I want kvm to be also able to access my LAN. Therefor I create a bridge interface:

iface br0 inet dhcp        bridge_ports eth0 tap0        bridge_maxwait 0

Which I bring up via DHCP. Of course I’ll have to change eth0 also:

iface eth0 inet manual

Finually make sure they are brought up in the right order:

auto lo eth0 tap0 br0

In total this gives an /etc/network/interfaces like this:

auto lo eth0 tap0 br0

iface lo inet loopback

iface br0 inet dhcp        bridge_ports eth0 tap0        bridge_maxwait 0

iface eth0 inet manual

iface tap0 inet manual        pre-up tunctl -b -u <my_user_name> -t tap0        pre-up ifconfig tap0 up        post-down tunctl -d tap0

Finually edit the file /etc/kvm/kvm-ifup and put everything in it in comments.
Now bring down the network and bring it up again:

ifdown -a
ifup -a

And then start the kvm:

kvm -net nic -net tap,ifname=tap0 -hda vdisk.qcow -m 256 -localtime

Once booted, log in and change the /etc/network/interfaces file in the image to use DHCP:

iface eth0 inet dhcp

If you bring down the net and bring it up again (within the kvm!):

ifdown -a
ifup -a

you should get a DHCP lease from your LAN and the kvm is available on the LAN.

Now it’s time to start using it!
