setup host

enable nested kvm edit /etc/modprobe.d/kvm.conf: 

# For Intel
options kvm_intel nested=1
#
# For AMD
#options kvm_amd nested=1

if using rhel9 as host install the following repo: 

dnf copr enable ligenix/enterprise-qemu-spice

then install libvirt and qemu-kvm: 

yum install -y libvirt qemu-kvm guestfs-tools nbd

enable and start libvirtd daemon: 

systemctl enable libvirtd && systemctl start libvirtd

create the following directory under /var/lib/libvirt/images: 

mkdir /var/lib/libvirt/images/openstack 
cd /var/lib/libvirt/images/openstack

configure debian image

download debian bullseye: 

wget http://cdimage.debian.org/cdimage/cloud/bookworm/latest/debian-12-generic-amd64.qcow2

for baremetal download the iso: 

http://mirrors.ocf.berkeley.edu/debian-cd/12.9.0/amd64/iso-cd/debian-12.9.0-amd64-netinst.iso

resize cloud image: 

cp debian-12-generic-amd64.qcow2 debian-12-generic-amd64_100G.qcow2
qemu-img resize debian-12-generic-amd64_100G.qcow2 +98G

expand image partition: 

virt-resize --expand /dev/sda1 debian-12-generic-amd64.qcow2 debian-12-generic-amd64_100G.qcow2

set root password for image: 

virt-sysprep -a debian-12-generic-amd64_100G.qcow2 -q --root-password password:livinglavidalinux

mount cloud image to pre-configure network: 

modprobe nbd
qemu-nbd -c /dev/nbd0 debian-12-generic-amd64_100G.qcow2
kpartx -a /dev/nbd0
mkdir /mnt/cloudimg
mount /dev/mapper/nbd0p3 /mnt/cloudimg

mount -o bind /dev /mnt/cloudimg/dev
mount -o bind /dev/pts /mnt/cloudimg/dev/pts
mount -o bind /run /mnt/cloudimg/run/
mount --bind /etc/resolv.conf /mnt/cloudimg/etc/resolv.conf

enter debian node environment using chroot: 

chroot /mnt/cloudimg

inside debian environment load the following profile: 

source /etc/profile
export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

add this parameters to grub configuration /etc/default/grub: 

GRUB_CMDLINE_LINUX="biosdevname=0 net.ifnames=0"

update grub configuration: 

update-grub

disable and remove systemd-networkd: 

systemctl disable systemd-networkd.socket systemd-networkd \
systemd-networkd-wait-online

install legacy networking: 

apt update && apt install -y ifupdown

remove netplan.io: 

apt -y purge --auto-remove netplan.io

remove systemd-resolved: 

apt -y purge --auto-remove systemd-resolved

setup ssh-server configuration: 

dpkg-reconfigure openssh-server

change sshd config to allow root user and password connection: 

sed -i 's/PasswordAuthentication no/PasswordAuthentication yes/g' /etc/ssh/sshd_config
sed -i 's/#PermitRootLogin prohibit-password/PermitRootLogin yes/g' /etc/ssh/sshd_config

update system: 

apt update && apt upgrade -y

exit chroot: 

exit

umount image when finish configuration: 

umount /mnt/cloudimg/etc/resolv.conf
umount /mnt/cloudimg/proc
umount /mnt/cloudimg/dev/pts
umount /mnt/cloudimg/dev
umount /mnt/cloudimg/run

dmsetup remove /dev/mapper/nbd0p1
dmsetup remove /dev/mapper/nbd0p2
dmsetup remove /dev/mapper/nbd0p3

create nodes images

create storage images for openstack nodes: 

cp debian-12-generic-amd64_100G.qcow2 debian-12_openstack-node1.qcow2
cp debian-12-generic-amd64_100G.qcow2 debian-12_openstack-node2.qcow2
