Installing Haiku-os on a partition from within Qemu

I build my own haiku images so this is a easy way to install and test on my machine

add new partition with fdisk /dev/sda
change the type to bfs
start qemu

sudo qemu -cdrom haiku-cd.iso -hda /dev/sda4 -m 1024

start installer , format the partition and then do the real install on that raw partition

stop the qemu when it finishes ctrl-c

start the new installed machine

sudo qemu  -hda /dev/sda4 -m 1024

later you can add it in grub menu to start it from there directly
