configure os

download latest archlinux cloud image: 

wget https://linuximages.de/openstack/arch/arch-openstack-LATEST-image-bootstrap.qcow2

make sure we have libguestfs installed: 

pacman -S libguestfs guestfs-tools

resize image: 

cp arch-openstack-LATEST-image-bootstrap.qcow2 arch-openstack-LATEST-image-bootstrap_100G.qcow2
qemu-img resize arch-openstack-LATEST-image-bootstrap_100G.qcow2 +99G

expand image: 

virt-resize --expand /dev/sda1 arch-openstack-LATEST-image-bootstrap.qcow2 arch-openstack-LATEST-image-bootstrap_100G.qcow2

change password: 

virt-sysprep -a arch-openstack-LATEST-image-bootstrap_100G.qcow2 -q --root-password password:vidalinux

uninstall cloud-init: 

virt-sysprep -a arch-openstack-LATEST-image-bootstrap_100G.qcow2 --run-command "pacman -R cloud-init --noconfirm"

on centos copy the image to this directory: 

cd /var/lib/libvirt/images/

mount image: 

qemu-nbd -c /dev/nbd0 arch-openstack-LATEST-image-bootstrap_100G.qcow2 
kpartx -a /dev/nbd0
mkdir /mnt/archlinux
mount /dev/mapper/nbd0p1 /mnt/archlinux
mount -o bind /dev /mnt/archlinux/dev
mount -o bind /proc /mnt/archlinux/proc

enter enviroment with arch-chroot: 

arch-chroot /mnt/archlinux

initialize the pacman keyring and populate signing keys: 

pacman-key --init
pacman-key --populate archlinux

configure /etc/hosts: 

cat > /etc/hosts << EOF
127.0.0.1 localhost
10.44.1.44 archlinux
EOF

edit /etc/ssh/sshd_config: 

sed -i 's/#PasswordAuthentication yes/PasswordAuthentication yes/g' /etc/ssh/sshd_config
sed -i 's/#PermitRootLogin prohibit-password/PermitRootLogin yes/g' /etc/ssh/sshd_config

enable sshd service: 

systemctl enable --now sshd

configure hostname: 

hostnamectl set-hostname archlive

configure timezone: 

timedatectl set-timezone America/Puerto_Rico

network configuration: 

ip addr add 192.168.24.10/24 dev eth0
ip route add default via 192.168.24.254
rm /etc/resolv.conf
echo "nameserver 4.2.2.1" > /etc/resolv.conf
echo "nameserver 4.2.2.2" >> /etc/resolv.conf

stop and disable systemd-resolved: 

systemctl disable systemd-resolved && systemctl stop systemd-resolved

update entire os: 

pacman -Syuu --noconfirm

install packages: 

pacman -Sy curl vim screen nano net-tools bind-tools networkmanager ebtables ethtool wget unzip socat conntrack-tools parted gptfdisk lvm2 git

configure networkmanager: 

cat > /root/net << EOF
systemctl start NetworkManager && systemctl enable NetworkManager
nmcli con del eth0
nmcli con del Wired\ connection\ 1
nmcli con add con-name eth0 ipv4.method manual type ethernet ifname eth0 ipv4.addresses 10.44.1.44/24 ipv4.gateway 10.44.1.1 ipv4.dns 4.2.2.1,4.2.2.2 autoconnect yes
EOF

install chrony: 

pacman -S chrony --noconfirm

enable and start chrony: 

systemctl enable chronyd

reboot machine: 

reboot

umount qcow2 image: 

umount /mnt/archlinux/proc
umount /mnt/archlinux/dev
umount /mnt/archlinux 
nbd-client -d /dev/nbd0
dmsetup remove /dev/mapper/nbd0p1
