virtomate 0.1.0

Virtomate
Virtomate is a handy command-line application for managing virtual machines with libvirt. It runs on any Unix-like system with Python 3.10 and libvirt 9.0 (or newer) installed.
Accomplish complex tasks like cloning virtual machines with ease:
$ virtomate domain-clone --mode linked ubuntu-24.04 my-clone

Or run a command on the guest without SSH:
$ virtomate -p guest-run ubuntu-24.04 -- apt-get update
{
"exit_code": 0,
"signal": null,
"stderr": null,
"stderr_truncated": false,
"stdout": "Hit:1 http://archive.ubuntu.com/ubuntu noble InRelease\nHit:2 http://archive.ubuntu.com/ubuntu noble-updates InRelease\nHit:3 http://archive.ubuntu.com/ubuntu noble-backports InRelease\nHit:4 http://security.ubuntu.com/ubuntu noble-security InRelease\nReading package lists...\n",
"stdout_truncated": false
}

Virtomate's scripting-friendly interface makes automating administrative tasks a breeze. Pipe its JSON output to jq to extract the information you need and combine it with any other tool. Emptying a storage pool becomes a single line of code:
$ virtomate volume-list boot | jq '.[].name' | xargs -i virsh vol-delete {} --pool boot

Even if virtual machines are running on a remote host, don't let that stop you. Virtomate can connect to other hosts using remote URIs:
$ virtomate -c qemu+ssh://[email protected]/system -p domain-list

Development
Prerequisites

Rye 0.28 or newer
Python 3.10 or newer
libvirt 9.0 or newer
Packer 1.10 or newer

To run the complete test suite, including the functional tests, you need a machine with an x86 CPU running Linux. Other operating systems like BSD or macOS might work but have not been tested.
Preparation
To run the complete test suite, including the functional tests, you have to build a couple of virtual machine images and configure libvirt accordingly. This is an optional step, and you can skip it if you do not want to run the functional tests.
Install libvirt, QEMU
Refer to the instructions of the respective Linux distribution:

Debian
Fedora
Ubuntu

Check that the command-line tools virsh and qemu-img are on PATH and working.
Create Storage Pools
The test suite expects the presence of the following storage pools:

default in /var/lib/libvirt/images
nvram in /var/lib/libvirt/qemu/nvram

If they do not exist, you can create them as follows:
$ virsh pool-define-as default dir --target /var/lib/libvirt/images
$ virsh pool-autostart default
$ virsh pool-build default
$ virsh pool-start default

$ virsh pool-define-as nvram dir --target /var/lib/libvirt/qemu/nvram
$ virsh pool-autostart nvram
$ virsh pool-build nvram
$ virsh pool-start nvram

Create Virtual Machine Images
The functional tests require some virtual machine images to run. There are Packer templates in packer/ to create them in a couple of minutes:
$ pushd packer
$ packer build simple-bios.pkr.hcl
$ packer build simple-uefi.pkr.hcl
$ popd

Packer will save the virtual machine images to packer/dist.
Then, import them into libvirt by running:
$ sudo ./prepare-pool.sh packer/dist

Create a Build
$ rye build

This will create a source distribution (.tar.gz) and a wheel (.whl) in the folder dist of the source root.
Run the Tests
To run the unit tests, run:
$ rye test

Run the Functional Tests
WARNING: Running the functional tests can cause data loss. The test suite will treat all virtual machines and storage volumes whose names start with virtomate- as test artefacts and delete them after each test.
To run the functional tests, activate the virtual environment with source .venv/bin/activate (on Unix-like operating systems) or . .\env\Scripts\activate.ps1 on Windows. Then run:
$ rye test -- --functional

Functional tests require a working libvirt installation with QEMU. See the section Preparation above.
By default, the functional tests connect to qemu:///system. If your local user cannot access qemu:///system, adding it to the group libvirt is usually sufficient.
To run the functional tests against a different libvirt instance, define the environment variable LIBVIRT_DEFAULT_URI accordingly. See the libvirt documentation on Connection URIs on how to do this.
