Public bug reported:
Confirmed on:
- RDO stable/2023.1 (antelope)
- Almalinux 9, kernel 5.14.0-284.18.1.el9_2.x86_64
- Neutron 22.0.2 (RDO)
- OVN 22.12 (from CentOS SIG)
How to reproduce:
- Have a functioning instance which gets its IP address from DHCP
- Ensure that you have a user that can log in through console
- Remove default egress rules ("any" to 0.0.0.0/0)
- Reboot instance
- Watch instance not having IP
Workaround:
- Add a security group rule that allows egress udp 67:68 to 0.0.0.0/0
will ensure that the instance gets an IP.
