Libvirt OpenTofu provider

dmacvicar/libvirt

• dmacvicar/libvirt provider

Server setup

• Follow debian wiki:installation

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. Related issues:
  • Support Volume Resizing from Base Volume
  • Unable to set disk size when deploying from cloud image

OpenTofu setup

Install on laptop (for cloud-init disk):

sudo pacman -S cdrtools

Cloud-init

• cloud-init modules

Issues

• Changing some resources lead to their destruction and recreation
  • i.e. changing vcpus
  • see Which domain attributes not require replacement?
  • or libvirt_pool path => target.path migration (0.8.x) without destroying pool?
• 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
