Not sure I understand. You can use Ansible module to list VMs, you

can use ovirt_vms _facts[1] module.

For example to get only stopped VMs, you can use following:

- name: Get stopped VMs

ovirt_vms_facts:

    auth:

      url: https://ovirt.example.com/ovirt-engine/api

      username: admin@internal

      password: password

      ca_file: /etc/pki/ovirt-engine/ca.pem

    pattern: "status = down"

I want a list of vms sorted by any possible attributes, i.e. sorted by datacenter or cluster, not only by status.

For example, ovirt_vms_facts doesn't allow to get the datacenter the vm belongs to , and the pattern filter doesn't return a list of vms as expected:

- hosts: localhost
connection: local
tasks:
- name: Get stopped VMs
    ovirt_vms_facts:
      auth:
        url: https://acore.v100.abes.fr/ovirt-engine/api
        username: admin@internal
        password: ovirt123
        insecure: true
        pattern: name=centos* and cluster=west
- debug:
      var: ovirt_vms
- shell: echo "{{ ovirt_vms.name }}"

Ok, I understand, now.

You have few options here.

If you want for example only VMs from datacenter 'X', you can use following:

- hosts: localhost
connection: local
tasks:
- name: Get VMs from datacenter X
    ovirt_vms_facts:
      pattern: datacenter=X
      auth:
        url: https://acore.v100.abes.fr/ovirt-engine/api
        username: admin@internal
        password: ovirt123
        insecure: true
- debug:
      msg: "{{ ovirt_vms | map(attribute='name') | list }}"

How can I successfully display this list of vms like described here :

name description returned type sample

ovirt_vms List of dictionaries describing the VMs. VM attribues are mapped to dictionary keys, all VMs attributes can be found at following url: https://ovirt.example.com/ovirt-engine/api/model#types/vm. On success. list

About the python SDK:

list_vms.py could be what I expect, but vm.datacenter_name doesn't exist

name	description	returned	type	sample
ovirt_vms	List of dictionaries describing the VMs. VM attribues are mapped to dictionary keys, all VMs attributes can be found at following url: https://ovirt.example.com/ovirt-engine/api/model#types/vm.	On success.	list

Yes, because the 'data_center' parameter isn't part of the VM type. Take a look here[1],

you will find there all attributes the VM has. As you can see there is no 'datacenter', but

there is a 'cluster', but as said in documentation, it's just a reference to the cluster. That

means that it contains the ID of the cluster and the 'href' to the cluster, so you can get

the cluster object by following that reference using this code:

vm_cluster = connection.follow_link(vm.cluster)

print vm_cluster.name

# Same for datacenter:

vm_dc = connection.follow_link(vm_cluster.data_center)

print vm_dc.name

What you need to understand is, what is the difference between the 'full'

object and the reference to the object. It's good to take a look at the XML

output of the API and learn to read the API specification documentation,

when working with oVirt Ansible and Python SDK.

Thanks, I knew this python script, but I believed it was possible to do the same with an ansible module.

That's mean we need several tools to do different tasks, it is not a very convergent way to proceed... but it is feasable.

Hello,

I didn't find anyway to easy list all my vms thanks to the ansible modules...
I tried the ovirt4.py script which is able to list the whole facts, so vms list, when the number of them is small in a test datacenter, but in a production datacenter, I get an issue:

File "./ovirt4.py", line 262, in <module>
main()
File "./ovirt4.py", line 254, in main
vm_name=args.host,
File "./ovirt4.py", line 213, in get_data
vms[name] = get_dict_of_struct(connection, vm)
File "./ovirt4.py", line 185, in get_dict_of_struct
(device.name, [ip.address for ip in device.ips]) for device in devices
File "./ovirt4.py", line 185, in <genexpr>
(device.name, [ip.address for ip in device.ips]) for device in devices
TypeError: 'NoneType' object is not iterable

This error was fixed already, try to download latest ovirt4.py file.

The other way is to use fatcs[1] module.

[1] http://docs.ansible.com/ansible/ovirt_vms_facts_module.html

What is the simpliest way to get this basic information with sdk4??? (with sdk3 : ovirt-shell -E "list vms")

Please take a look at the following example:

https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/list_vms.py
