The ovirt API documentation I've found is really poor, I don't know if someone here has already got the same need and had a good solution.

Did you try one of the SDKs?

Also the ansible modules are useful for many cases.

Why not? You're the next devops :) I was used to use ovirt-shell (removed from 4.4), and instead of it I control now all my vms with ansible playbooks: * consultation with ovirt-*_inf with appropriate filters (combine , dict2items) and conditions (when, until) * interaction with other modules (with present/absent statement for all parameters) I precise I am not a developer but once I took the habit with a proper environment (venv, IDE, loops, structured playbook and roles, dict struct, etc..), I was able do what I want, or rather what the API let me do. Before begining, I should advice you to take the time to study the structure of the output of the registered variable Here is a piece of my commonly used playbooks to check status of wanted vms: - name: template ovirt pour tester les modules hosts: localhost connection: local tasks: - block: - include: ovirt_auth.yaml tags: auth,change - name: vmfacts ovirt_vm_info: auth: "{{ ovirt_auth }}" pattern: "name=vm5 or name=vm8" register: vm_info - debug: var=vm_info.ovirt_vms # msg: "{{vm_info.ovirt_vms | map(attribute='status')|list}}" - name: "Génération d'un dictionnaire avec combine" set_fact: vm_status: "{{ vm_status|default({})|combine({item.name: item.status}) }}" loop: "{{vm_info.ovirt_vms}}" when: item.status == "up" - debug: msg: "{{vm_status}}" always: - include: ovirt_auth_revoke.yaml tags: auth,change Good luck!

This is up to you, of course.

For one that uses the python SDK, see ovirt-system-tests. The SDK itself also has a very useful collection of examples.

I am in a similar boat as you. I wrote some management scripts around ovirt-shell when I first started using ovirt (4.0), in order to mimic some vmware-server features that I needed. I run a single-host hosted-engine environment, so when the system boots up (e.g. from a power failure) I wanted all my VMs to auto-start, and to start in the correct order. I can't use the ovirt power management utilities because it's only a single host. So I wrote a relatively small script around ovirt-shell that would do the following: 1) Wait for the engine to respond 2) Wait for the storage to come online 3) Start my VMs, with appropriate order and delay between (e.g., ensure my DNS server and KDC come up before other VMs) I know that SOME of these features are now in Ovirt (and I think they are even in 4.4), but my understanding is that they only return the system to previous state and wont auto-start a VM that was cleanly shut down. Also the ordering is, IIUC, somewhat course (low/medium/high). At this point I plan to delay my deployment of 4.4 or beyond because what I have in 4.3 is working (still), and frankly I have no interest in learning Ansible or Python just to replace what should be a relatively simple script. I honestly find it very sad that the developers wont up-port ovirt-client to SDK4. If SDK4 is "so good" vs SDK3 then I don't see why it would be hard to do that. And if it IS that hard to do, then how do they expect us to use it? Maybe I will find some time to play with OV4.4 on a test system in order to play with the auto-start features. In my copious amounts of free time. :( Thanks, -derek -- Derek Atkins 617-623-3745 derek@ihtfp.com www.ihtfp.com Computer and Internet Security Consultant

Yes. The devs call it "SDK4", which has been around for a few releases now. The CLI, however, uses SDK3, which was removed from Ovirt 4.4. Search for "ovirt-shell". -derek On Fri, February 28, 2020 10:47 am, Eugène Ngontang wrote:

That's not the point. I was not part of the decision to drop ovirt-shell, but think it made sense. If you need to do complex stuff with it, you practically spend time on learning a new language, which is oVirt-specific, and so won't be useful for you for anything else you might do in the future. If you instead spend time on learning either python or ansible, you learn languages that are useful for other things you might want to automate. I think both of them suite very well the "sysadmin sometimes playing a developer" role. (I played that role myself for ~ 15 years, before joining Red Hat as a "real" developer, so speak from experience...) If you miss ovirt-shell itself (I guess mainly because for very simple things you could do stuff in a single command-line, and that's probably uglier to do with either ansible or python (although doable)), the below project was already mentioned in this thread elsewhere. I never tried it myself: https://github.com/karmab/kcli
