Fixed In Version:	otopi-1.8.4-1.el7ev	Doc Type:	Bug Fix
Doc Text:	Previously, with Red Hat Virtualization 4.3 on RHEL 7, if the system had Python 3 installed, otopi used Python 3. This caused relevant tools such as engine-setup and ovirt-host-deploy to fail. The current release fixes this issue: Now, even with Python 3 installed, otopi uses Python 2, enabling otopi-based tools such as engine-setup and ovirt-host-deploy to succeed. In the next minor version, 1.9, otopi should support Python 3 on RHEL 8 and Fedora.	Story Points:	---

Description RHV bug bot 2019-09-23 13:07:04 UTC

+++ This bug is an upstream to downstream clone. The original bug is: +++
+++   bug 1751324 +++
======================================================================

Description of problem:
As previously described with Bug 1688811, an python3 will cause Otopi to pick it first, but for all the system libraries only exist as Python2 code on CentOS 7

With Python3 being included in the standard, the argument cited for "wontfix" in the bug 1688811 may need to be revised.

Version-Release number of selected component (if applicable):
oVirt 4.3.5.2 otopi 1.8.3-1.el7

How reproducible:
, try to add it as a new host to oVirt,

Steps to Reproduce:
1. Install python3 on target host-to-add
2. try to add host to oVirt engine
3. /var/log/ovirt-engine/host-deploy/ovort-host-deploy<unique-id>.log will contain error messages that rpmUtils could not be imported.

Actual results:
Host installation fails quickly, needs to be removed immediately or there will be followup problems, because it cannot go into maintenance for proper removal

Expected results:
Host installed and usable

Additional info:
took more than three weeks to track down, very hard to find

Sandro - do we want this in 4.3? I think so.
