This is just to get things started, and eventually we will work on a more elaborate test bed.

  1. ✅ Create prechecks for the system to verify:
    1. Debian-based Linux Distribution 1
    2. Supported CPU architecture: AMD, Intel, RISC-V, MIPS, and ARM
    3. Virtualization support
    4. Packages for KVM/QEMU and Libvirt daemon installed
    5. virt-lightning requirements
      1. Python 3.8 or greater
      2. Python3 libvirt binding via python3-libvirt and other Linux python packages for virt-lightning
      3. Running libvirtd with system (not session) access via qemu:///system handle.
      4. Default storage directories exist and have the proper permissions.
  2. ✅ Set up basic virt-lightning.yaml that creates a basic debian-13 vm used for testing.
  3. ✅ Create Ansible playbook that runs through some basic modification steps.
  4. ✅ Document the basic testing process in the README.md.
  5. Create clear documentation around the virtualization stack and technologies used here.

  1. We require a Debian-based Linux distribution to simplify verification of libraries by only assuming apt and other system calls to verify system state. This will only be used for the build distributions and may include other Linux distributions moving forward. ↩︎

Set up a precheck.py file that does all the checks and walks the user to manually verify the machine to ensure the testbed is supported and install any missing packages or setup is needed. The output looks like this when all goes well:

$ sudo python precheck.py 
=== Neticenters Testing Infrastructure Check ===
✓ Debian-based Linux distribution with apt detected
✓ Supported CPU architecture detected: x86
✓ AMD CPU supporting AMD-V
✓ Python 3.8 or greater is installed
✓ Required libvirt packages are installed
✓ Successfully connected to libvirt daemon at qemu:///system
✓ All virt-lightning requirements are installed
✓ All virt-lightning directories are properly configured

✓ All checks passed for neticenters testing and development.
