Libvirt Terraform provider

• Run Debian 11 (Bullseye) on KVM using Qcow2 Cloud Image
• Outdated, but still interesting: camptocamp/terraform-libvirt-k3s Although k3os is dead
• dmacvicar/libvirt provider

Server setup

• Follow debian wiki:installation
• Unfortunatly, LVM storage pools can't be created yet with dmacvicar/libvirt

Create libvirt directpry storage pool (LVM doesn't work, see below):

virsh pool-create-as default  --type dir --target /var/lib/libvirt/images
virsh pool-autostart default

Issues with LVM storage pool:

• Using a backingStore as baseimage and creating a bigger root LVM volume doesn't work, therefore sticking with directory storage pools for now. Since LVM storage pool support is still not merged, I refrained from opening an issue for this. Related issues:
  • Support Volume Resizing from Base Volume
  • Unable to set disk size when deploying from cloud image

Terraform setup

Install on laptop (for cloud-init disk):

sudo pacman -S cdrtools

Cloud-init

• cloud-init modules

Issues

• Images are created with root user and I get access denied #978 Solution: Disable apparmor in /etc/ibvirt/qemu.conf
• Domain cannot get installed because of apparmor: See security/apparmor.md
