1. Verify Your Device already follow step on

2. Create Pool

Store Network

nano net-10.10.10.xml
'''
<network>
  <name>net-10.10.10</name>
  <forward mode='route'/>
  <bridge name='virbr10' stp='on' delay='0'/>
  <ip address='10.10.10.1' netmask='255.255.255.0'>
    <dhcp>
      <range start='10.10.10.2' end='10.10.10.254' />
    </dhcp>
  </ip>
</network>
'''
virsh net-create net-10.10.10.xml
virsh net-destroy net-10.10.10
virsh net-undefine net-10.10.10
virsh net-define net-10.10.10.xml
virsh net-start net-10.10.10
virsh net-autostart net-10.10.10

Store Images

mkdir /images
virsh pool-define-as images dir - - - - "/images"
virsh pool-build images
virsh pool-start images
virsh pool-autostart images

Store VM disk

mkdir /vms
virsh pool-define-as vms dir - - - - "/vms"
virsh pool-build vms
virsh pool-start vms
virsh pool-autostart vms

Verify it

virsh net-list --all
virsh pool-list --all

3. TVGen Binary

git clone https://github.com/mrofiq466/TVGen-Master.git
chmod +x TVGen-Master/tvgen
mv TVGen-Master/tvgen /usr/local/bin/
tvgen -h

4. Prepare Enviroment

Set AppArmor

nano  /etc/apparmor.d/libvirt/TEMPLATE.qemu
'''
#include <tunables/global>
profile LIBVIRT_TEMPLATE flags=(attach_disconnected) {
  #include <abstractions/libvirt-qemu>
/**.qcow{,2} rwk,
/**.img rwk,
}
'''
apparmor_parser -r /etc/apparmor.d/libvirt/TEMPLATE.qemu
systemctl reload apparmor

Image

wget https://cloud-images.ubuntu.com/releases/focal/release/ubuntu-20.04-server-cloudimg-amd64.img
cp ubuntu-20.04-server-cloudimg-amd64.img /images/ubuntu2004.img
virsh pool-refresh --pool images

Create file variable

You can edit/ copy format from test1 and test2, Read detail.

nano test1.txt
'''

tvgen demo test1.txt
cd demo
terraform init
terraform apply -auto-approve

5. Access Instance

virsh net-dhcp-leases default
virsh list
ssh 10.10.10.3 -l tshoot    # password is "help" this user have sudo access
virsh console demo-tvgen1   # use user "root" and psw "password" 
ssh 10.10.10.3 -i ~/id_rsa  # ssh password less

Noted

File variable it most case-sensitive.
Make sure AppArmor config.
You can use images again from /images to another instance. check on virsh vol-list vms.
When you create another instance make sure the domain name is different.
