setup hosts

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

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

copy and pasted the following on your shell:

cat > /usr/local/bin/openstack << "EOF"
#!/bin/bash 

VMS="openstack-node1-debian10
openstack-node2-debian10
openstack-node3-debian10

if [ $1 = start ]; 
then
for u in ${VMS}; do virsh start $u; done
fi  
 
if [ $1 = destroy ];
then
for u in ${VMS}; do virsh destroy $u; done
fi
EOF

if [ $1 = shutdown ];
then
for u in ${VMS}; do virsh shutdown $u; done
fi
EOF

fix permissions:

chmod +x /usr/local/bin/openstack

start virtual machines using the script:

openstack start

configure node1

mount cloud image to pre-configure network:

modprobe nbd
qemu-nbd -c /dev/nbd0 openstack-node1.qcow2 
kpartx -a /dev/nbd0
mkdir /mnt/cloudimg
mount /dev/mapper/nbd0p1 /mnt/cloudimg
mount -o bind /dev /mnt/cloudimg/dev
mount -o bind /proc /mnt/cloudimg/proc

enter debian node environment using chroot:

chroot /mnt/cloudimg

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

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

update grub configuration:

update-grub

configure network on node1:

cat > /etc/network/interfaces << EOF
auto lo eth0 eth1 eth2 eth3
iface lo inet loopback
# eth0
iface eth0 inet manual
up ip link set dev eth0 up
down ip link set dev eth0 down
# eth1
iface eth1 inet static
address 192.168.88.58/24
gateway 192.168.88.1
dns-nameservers 192.168.88.64
# eth2
iface eth2 inet static
address 10.10.88.58/24
# eth3
iface eth3 inet manual
up ip link set dev eth3 up
down ip link set dev eth3 down
EOF

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

exit chroot:

exit

umount image when finish configuration:

umount /mnt/cloudimg/proc
umount /mnt/cloudimg/dev
umount /mnt/cloudimg 
nbd-client -d /dev/nbd0
dmsetup remove /dev/mapper/nbd0p1
dmsetup remove /dev/mapper/nbd0p14
dmsetup remove /dev/mapper/nbd0p15

start node1 virtual machine:

virsh start openstack-node1-debian10

connect to node1 using ssh:

ssh root@192.168.88.58

set hostname:

hostnamectl set-hostname oscpnode1

set timezone:

timedatectl set-timezone America/Puerto_Rico

configure node2
