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.
Description of problem:
In aws, after removed 2nd ip from network interface, nm-cloud-setup cannot removed it from eth0 automatically.
Below is an example:
# curl http://169.254.169.254/latest/meta-data/local-ipv4
10.116.1.150
# ip addr show eth0
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9001 qdisc mq state UP group default qlen 1000

# rpm -q NetworkManager-cloud-setup
NetworkManager-cloud-setup-1.30.0-0.7.el8.x86_64
Version-Release number of selected components (if applicable):
RHEL Version:
RHEL8.4(4.18.0-277.el8.x86_64 )
How reproducible:
100%
Steps to Reproduce:
1. Start a RHEL-8.4 with nm-cloud-setup installed.
2. Check addr in eth0
Actual results:
The unassigned ip is not removed as expected.
Expected results:
Auto remove unassigned ip.
Additional info:
- ip addr can be set automatically if add new ip
- Amazon Linux2 can do it automatically in adding and removing ips.
Could you please provide a complete debug log of NetworkManager and nm-cloud-setup?
For NetworkManager, see https://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/contrib/fedora/rpm/NetworkManager.conf#n28 for how to enable level=TRACE logging.
For nm-cloud-setup, see `systemctl cat nm-cloud-setup.service` for how to set "Environment=NM_CLOUD_SETUP_LOG=TRACE": by doing `systemctl edit nm-cloud-setup.service` and edit the Environment.
Afterwards, restart both services (or maybe reboot, to get a clean, complete log).
Finally, please provide the complete journal and not separate. Either `journalctl -b 0 -u NetworkManager -u nm-cloud-setup` or just the entire `journalctl -b 0`.
Thank you!

Please check '20210128_nm_debug.log' for details, '10.116.1.65' is the 2nd ip which was unassigned already.
