Description of problem:

oVirt Node 4.3.7 is unusable because of multiple problems in low-level system libriaries.

Version-Release number of selected component (if applicable): 4.3.7

How reproducible: Always

Steps to Reproduce:
1. Install 4.3.7 ( yum makecache ; yum update )
2. Change default layer to ovirt-node-ng-4.3.7-0.20191121.0+1
3. Reboot 

Actual results:

Node is unusable. Multiple commands are crashing i.e.

1. firewalld - undefined symbols

# firewall-cmd --get-default-zone
Traceback (most recent call last):
  File "/usr/bin/firewall-cmd", line 24, in <module>

    from . import _gi

3. Node activation - undefined symbol

When trying to activate Node it falls in NotOperational state. NFS Storage Domains can't be activated. In /var/log/vdsm/vdsm.log I see such tracebacks:

Expected results:

Node should work normally after upgrade.

Additional info:

Varsion 4.3.7 in unusable. I had to rollback to 4.3.5. After rolling back everything works as before. Currently on that upgraded node I have such layers:
