Test ISO with KVM

Check for virtualization support

egrep '(vmx|svm)' --color=always /proc/cpuinfo

If you get back 'vmx' (Intel) or 'svm' (AMD) load kvm module

sudo modprobe kvm-intel
or for Amd-Prozessor
sudo modprobe kvm-amd

Test ISO (insert full name for "rg-grml_.iso"!):

kvm -cdrom rg-grml_.iso -m 1024

  Used directory-tree

LLMM=/lib/live/mount/medium
LLMMI=$LLMM/boot/isolinux
/lib/live/mount/medium => all of the CD
$LLMM/boot/grml32full/initrd.img => compressed initramfs
$LLMM/live/grml32-full/grml32-full.squashfs => compressed filesystem Image
/opt/grml/init_rd32 => decompressed initramfs
/opt/grml/remaster => decompressed filesystem Image
/opt/grml/iso => new remastered ISO (and
/usr/share/rg-grml => additional files for LXDE desktop

/home/grml/.local/share/applications =>
files for the special menu "GRML" and "Rescue-CD"

Mostly it is sufficient to use a 32bit OS for Rescue purpose; therefore only the "grml32-full Standard" has been changed to "Rescue_grml" with LXDE desktop. All the other options of Grml-CD are unchanged: "grml64-full Standard", "Additional boot entries for:" and "Further boot options:".

If you want to add other tools or documentations to the special menu GRML or Rescue-CD, look into the already available .desktop-files  to see which values are needed in the line "Categories=..".
