virt-builder Ansible or Bash

In this video I use a Ansible playbook and a bash script to deploy a guest virtual machine on quem kvm and review some of the pros and cons of each.

Script and playbook I used:

build_alma8.sh

#!/bin/bash
builderimage=alma-8.5
serverimage=alma8_server.img
servername=alma8_server
clientimage=alma8_client.img
clientname=alma8_client
workingdirectory=~/kvm_images/

cd $workingdirectory

#Build Server
sudo virt-builder $builderimage --hostname $servername --install "@Server,qemu-guest-agent" --ssh-inject root:file:y.pub --firstboot-command 'nmcli device connect ens3'  --edit '/etc/selinux/config: s/^SELINUX=.*/SELINUX=disabled/' --edit '/etc/sysconfig/qemu-ga: s/^BLACKLIST_RPC.*/#BLACKLIST_RPC/' --size 10G -o $serverimage

#Virt Install Server
sudo virt-install --name $servername --ram 4096 --vcpus=2 --disk path=$serverimage  --import --noautoconsole --channel unix,mode=bind,target_type=virtio,name=org.qemu.guest_agent.0

#Virsh List
virsh list
