Okay, I will try to help as much as I can, but sadly I don't understand
any perl.

Yes, it seems so.
I switched to tty2 right after class/20-hwdetect and vgdisplay
lvdisplay shows my whole lvm drive.

But even when I do:
# lvchange -an vg_guests
# vgchange -an vg_guests
# mdadm --stop /dev/md*

the problem still exists. The main difference is that disklist is
without raid or lvm stuff:
disklist: sda
sdb
sdc
sdd
sde

But then it looks similar:
# setup-storage -f /var/lib/fai/config/disk_config/KVM -d
1>/tmp/logfile 2>/tmp/logfile

But why has $this_mp an uninitialized value?
