Fixed In Version:	rhel-system-roles-1.7.3-3.el7_9	Doc Type:	Bug Fix
Doc Text:	Cause: In initscript mode, network role will create ifcfg file with `NM_CONTROLLED=no` instructing NetworkManager to mark the bridge as unmanaged. The follow up `down` and `absent` action of initscript provider will not change the NetworkManager's understanding on unmanaged state of this interface if the version of NetworkManager is 1.18. Fixes: Use `NM.Client.reload_connections_async()` to reload the configuration for nm provider on NetworkManager 1.18. Result: With the fixes, when switching the provider from the initscripts to the nm, the system will manage the bridge device.	Story Points:	---

Description Noriko Hosoi 2022-01-10 16:05:40 UTC

+++ This bug was initially created as a clone of Bug #2034908 +++

Description of problem:

The system role build `rhel-system-roles-1.7.3-2.el7_9` CI gating failed on
`tests_ethernet_nm.yml` (https://dashboard.osci.redhat.com/#/artifact/brew-build/aid/41866280?focus=id:7faf82018486-1)
and the failures indicated that the the created veth device is strictly unmanaged even if we explicitly set it to managed.

```
nmcli d set lsr27 managed yes

Dec 20 19:39:10 ibm-p8-kvm-03-guest-02.virt.pnr.lab.eng.rdu2.redhat.com NetworkManager[738]: <info>  [1640047150.4781] audit: op="device-managed" arg="managed" pid=19292 uid=0 result="success" (Journal)

(nmcli d)
DEVICE     TYPE      STATE         CONNECTION  
eth0       ethernet  connected     System eth0
peerlsr27  ethernet  disconnected  --          
lsr27      ethernet  unmanaged     --          
```

The situation arised only when the last test playbook is  `tests_ethernet_initscripts.yml`, when initscripts provider ran, the connection profile (/etc/sysconfig/network-scripts/ifcfg-lsr27) contained `NM_CONTROLLED=no`, which indicated that the device lsr27 is not managed by NM and at the end we cleaned the device and profile then when NM provider ran, we have to reload the connection because the connection profile was deleted (changed) previously. The test palybooks `tests_auto_gateway_nm.yml`, `tests_ipv6_nm.yml`, `tests_vlan _mtu_nm.yml` ran into the same issue.
