Bug 1776306

Can you provide the export ova ansible log? It is in:
/var/log/ovirt-engine/ova/ovirt-export-ova-ansible-20191125143657-storage-ge4-vdsm2.scl.lab.tlv.redhat.com-2269f616.log

The system has been reprovisioned from scratch and the issue is not seen anymore (checked rhv-4.4.0-6).
I suspect that the root cause for this issue is upgraded 4.3 -> 4.4 VM's.

I will try the upgrade flow and update.

Issue occurs all the time on another scale ENV which was upgraded(4.3->rhv 4.4.0-5).
I attatched engine + the requested correlating /ova/ovirt-export-ova-ansible log.

rhv-4.4.0-5 upgraded scale team env logs

Hi Liran, please check it out and ping me if you are missing something or ping Ilan Z. if you need his ENV to debug.
I also noticed this issue is not about a VM that got upgraded as in his ENV this issue also occured for new VM's created after upgrade to 4.4.

What I do notice is:
1) On newly reprovisioned ENV's from scratch(not upgraded) on rhv 4.4.0-6 the issue does not occur
2) On upgraded ENVs(4.3-> 4.4) the issue does occur 100% on any VM(old or newly created)

The problem is compatibility of python2 and python3.
The engine run python scripts that determined on build time which version to use(of the engine's machine).
When running those script on el8 based, which run python3, the script fails.
It will also fail when in the future we will run from el8 engine on el7 hosts(cluster version 4.3).

Fixing those script to run upon the destination machine's python and make the code compatible on both is the solution.

Liran, can you fill fixed in version please?

This bug is targeted to 4.4.1 and in modified state. can we re-target to 4.4.0 and move to QA?
