RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Fixed In Version: rhel-system-roles-1.13.0-1.el8
Doc Type: Bug Fix
Doc Text:
.The `nm` provider in the Networking System Role now correctly manages bridges Previously, if you used the `initscripts` provider, the Networking System Role created an `ifcfg` file which configured NetworkManager to mark bridge interfaces as unmanaged. Also, NetworkManager failed to detect followup `initscript` actions. For example, the `down` and `absent` actions of initscript provider will not change the NetworkManager's understanding on unmanaged state of this interface if not reloading the connection after the `down` and `absent` actions. With this fix, the Networking System Role uses the `NM.Client.reload_connections_async()` function to reload NetworkManager on managed hosts with NetworkManager 1.18. As a result, NetworkManager manages the bridge interface when switching the provider from `initscript` to `nm`.

Description Wen Liang 2021-12-22 13:19:33 UTC
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)
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.

How reproducible:

Steps to Reproduce:
1. Download rhel-guest-image-7.9-30.x86_64.qcow2 from http://download.hosts.prod.upshift.rdu2.redhat.com/released/rhel-6-7-8/rhel-7/RHEL-7/7.9/Server/x86_64/images/rhel-guest-image-7.9-30.x86_64.qcow2

2. `sudo TEST_DEBUG=1 TEST_SUBJECTS=rhel-guest-image-7.9-30.x86_64.qcow2 ansible-playbook -v -i /usr/share/ansible/inventory/standard-inventory-qcow2  ./tests/tests_ethernet_initscripts.yml ./tests/tests_ethernet_nm.yml`

Actual results:
Errors: "state:up persistent_state:present, 'lsr27': up connection failed: failure to activate connection: nm-manager-error-quark: No suitable device found for this connection"

Expected results:
No errors

:: [ 02:24:21 ] :: [   PASS   ] :: Test network/tests_ethernet_initscripts.yml (roles/rhel-system-roles.network/tests/tests_ethernet_initscripts.yml) with ANSIBLE-2.9 against RHEL_7_9_GA (Expected 0, got 0)
:: [ 02:25:38 ] :: [   PASS   ] :: Test network/tests_ethernet_nm.yml (roles/rhel-system-roles.network/tests/tests_ethernet_nm.yml) with ANSIBLE-2.9 against RHEL_7_9_GA (Expected 0, got 0)

[root@netqe18 Upstream-testsuite]# rpm -q rhel-system-roles
[root@netqe18 Upstream-testsuite]#

now the tests_ethernet_nm.yml playbook can pass after running tests_ethernet_initscripts.yml. Set this to verified
