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
