When I try to remove a VM like so...

• name: Remove the base VM from which we just created our template
  delegate_to: localhost
  ovirt_vms:
  auth:
  username: admin@internal
  password: XXXXX
  url: https://10.0.0.3/ovirt-engine/api
  insecure: true
  state: absent
  name: rhel7-base-vm
  wait: true

I get...

An exception occurred during task execution. The full traceback is:

The problem is that oVirt Python SDK doesn't check the HTTP return code. In this case it will get 404, with no body, so the XmlReader will fail. Actually this is bug in both oVirt Python SDK and the ovirt.py module in module_utils. Thanks for the report, I will fix it ASAP.

[machacekondra]

So I've checked and you are using Python SDK version 4.0.0 or lower, right? Please update to latest 4.0 version, which is 4.0.4, and it will work right:

https://pypi.python.org/pypi/ovirt-engine-sdk-python

[machacekondra]

Please close if oVirt Python SDK update solves the issue for you.

@atgreen Any news?

I know it's just remotely related, but I just experienced a similar error when playing around with ansible 2.3.0.0 (detached HEAD f15e1f25ae) last updated 2017/04/05 22:32:14 (GMT +200) and ovirt-engine-sdk-python-4.1.3.

When trying to run the ovirt_hosts_facts module the task aborted with:

TASK [Obtain oVirt hosts facts] ******************************************************************************************************
An exception occurred during task execution. To see the full traceback, use -vvv. The error was: Exception: Can't read first node
fatal: [localhost]: FAILED! => {"changed": false, "failed": true, "msg": "Can't read first node"}

The reason was, that I forgot to specify the ovirt-engine/api context in the url parameter. Thanks to your hint about the 404, I found my typo. Still I wouldn't say that the error message became any clearer with the recent versions of Ansible and the oVirt Python SDK.

Maybe this should be discussed in a different issue?

[machacekondra]

This is something we should fix in Python SDK for oVirt. Can you please open an issue here, requesting to do a URL check, whether it's in correct format? THanks!

Thanks for your reply. Just for reference, I opened https://bugzilla.redhat.com/show_bug.cgi?id=1440292
