Build debian netinstall iso

• put your public the in the folder
• user root with passowrd root (change later)

rename one of the files to preseed.cfg

• preseed.cfg.crypt
• preseed.cfg.plain

run gen.sh to build the ISO

./gen.sh <vm_name>

Run Terraform

terraform init
terraform plan sshfs -auto-approve
terraform apply -auto-approve
terraform destroy -auto-approve

FIX & TIPS

virsh list --all && virsh pool-list --all

delete old vm and pools

virsh destroy vm
virst undefine vm
virsh pool-destroy vm-pool
virsh pool-undefine vm-pool

If you change the name of the VM then you must delete all terraform* files

rm terraform*
