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

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

download debian bullseye:

wget https://cloud.debian.org/images/cloud/bullseye/latest/debian-11-generic-amd64.qcow2

for baremetal download the iso:

http://mirrors.ocf.berkeley.edu/debian-cd/11.7.0/amd64/iso-cd/debian-11.7.0-amd64-netinst.iso

resize cloud image:

cp debian-11-generic-amd64.qcow2 debian-11-generic-amd64_100G.qcow2
qemu-img resize debian-11-generic-amd64_100G.qcow2 +98G

set root password for image:

virt-sysprep -a debian-11-generic-amd64_100G.qcow2 -q --root-password password:livinglavidalinux

create storage images for openstack nodes:

cp debian-11-generic-amd64_100G.qcow2 openstack-node1.qcow2
cp debian-11-generic-amd64_100G.qcow2 openstack-node2.qcow2
cp debian-11-generic-amd64_100G.qcow2 openstack-node3.qcow2
cp debian-11-generic-amd64_100G.qcow2 openstack-node4.qcow2
cp debian-11-generic-amd64_100G.qcow2 openstack-node5.qcow2

create storage images for ceph cluster:

qemu-img create -f qcow2 ceph_storage_server1_1.img 100G 
qemu-img create -f qcow2 ceph_storage_server1_2.img 100G
qemu-img create -f qcow2 ceph_storage_server1_3.img 100G
qemu-img create -f qcow2 ceph_storage_server1_4.img 100G
qemu-img create -f qcow2 ceph_storage_server2_1.img 100G
qemu-img create -f qcow2 ceph_storage_server2_2.img 100G
qemu-img create -f qcow2 ceph_storage_server2_3.img 100G
qemu-img create -f qcow2 ceph_storage_server2_4.img 100G
qemu-img create -f qcow2 ceph_storage_server3_1.img 100G
qemu-img create -f qcow2 ceph_storage_server3_2.img 100G
qemu-img create -f qcow2 ceph_storage_server3_3.img 100G
qemu-img create -f qcow2 ceph_storage_server3_4.img 100G
