virt-installs VS terraform-provider-libvirt

have a look around my github i have a bunch of ansible/kickstart scripts there for almalinux. you can insert a kickstart into an iso (not great fun!) to do the basic setup and then pull down an ansible playbook to do the rest. but you're not going to be able to do much the same way arch does.

the way i do it is documented in my script, its basically a bridge with virt-clone and virt-sysprep, i don't use dhcp though.

Here is my setup, have a browse up a level too

I've got some complicated preseeds here if you want to compare

I have centos 5.11 running under KVM with virtio drivers, my script includes some notes here, should work with rhel5

if you're into making vm's from preseed, take a look around my repo as virt-install will blow your mind

I've done loads of RHEL9/alma9 kick-starts, some of which are unmodified from 8, have a look around my libvirt scripts

have a look around my github but the executive summary is:

i have a bunch of virt-install scripts, they configure the vm settings and then either run a kickstart/autoyast/preseed to install the OS, or import an image. similar to what virt-builder does.

Hi guys!I wanted to allotment with you a tool to provision a fully working OCP 4.x.y cluster in minutes using Ansible for automation, libvirt as virtualization provider and terraform as VMs templating and creation tool. https://github.com/kubealex/libvirt-ocp4-provisioner It will take care of all the infrastructure provisioning and OCP machines provisioning, starting and completing the UPI installation of a cluster. (IPI work in progress ;) ) To give a quick overview, this project will allow you to provision a fully working OCP stable environment, consisting of: * Bastion machine provisioned with: * dnsmasq (with SELinux module, compiled and activated) * dhcp based on dnsmasq * nginx (for ignition files and rhcos pxe-boot) * pxeboot * Loadbalancer machine provisioned with: * haproxy * OCP Bootstrap machine * OCP Master(s) VM(s) * OCP Worker(s) VM(s) From latest release, it also supports installing SNO on a single host! It also takes care of preparing the host machine with needed packages, configuring: * dedicated libvirt network (fully customizable) * dedicated libvirt storage pool (fully customizable) * terraform * libvirt-terraform-provider ( compiled and initialized based‏‏‎‏‏‎‏‏‎‏‏‎­on https://github.com/dmacvicar/terraform-provider-libvirt) PXE is automatic, based on MAC binding to different OCP nodes role, so no need of choosing it from the menus, this means you can just run the playbook, take a beer and have your fully running OCP 4.9.latest stable up and running. It has been tested on Fedora 3x and CentOS 7/8. Playing around with it and contributions to make it work even on different OSes is more than welcome, hope you enjoy it! Alex

I learned and got terraform to work with the KVM/Libvirt provider.

I saw Terraform with the dmacvicar/terraform-provider-libvirt provider, but sadly didn't get really warm with it. When some can explain to me how I can set up new images for every VM I would be very happy also there are more question in the pipeline. Sadly, the “Documentation” is not really that good. Maybe Terraform is also the wrong Application for me. I'm a little lost because I thought Terraform would be the big Solution I want and need, until now, not yet.

It looks like there was an issue dealing with "attaching an existing disk" to a terraform created VM. That's here: https://github.com/dmacvicar/terraform-provider-libvirt/issues/688

Nice. I’m straight KVM as it’s a mirror of work (my Lab) and I’m using the terraform-provider-libvirt provider. 20 minutes to fully build a site. Pretty cool.
