[ovirt-users] Ansible Modules for ovirt

[Jean Paul Gatt]

Thanks Ondra,

I will follow them on Github.

Keep up the good work. Also if there is any possibility to start testing the other modules(like managing networks) due to come out with ansible 2.3 please let me know.

Regards,

Jean Paul Gatt

This issue was already opened here:

  https://github.com/ansible/ansible-modules-extras/issues/3447

I will be very happy if you will take a look and tell what you think about the proposed fix.

I've opened an issue here:

  https://github.com/ansible/ansible-modules-extras/issues/3555

Feel free to comment there any additional requests regarding that issue.

Yes, that is the problem. To work reliably with disks, the only way is the ID. I will document it better, so users aren't confused.

I've opened following issue:

  https://github.com/ansible/ansible/issues/18650

I will work on it, feel free to comment any ideas there.
