Public bug reported: Hello,
We have an cloud service based on Openstack, we have provide IPv4 (dhcp) and IPv6 (static), on ubuntu 18.04 we detected that when is parsed instance-data.json it take info only for IPv4 and not get static records for IPv6. And related to this it not generate config for IPv6 we tested with netplan and ENI (ifupdown), all data in instance-data.json are present in the file. 2023-02-28 09:21:42,649 - util.py[DEBUG]: Reading from /sys/class/net/ens3/type (quiet=False) 2023-02-28 09:21:42,650 - util.py[DEBUG]: Read 2 bytes from /sys/class/net/ens3/type 2023-02-28 09:21:42,650 - networking.py[DEBUG]: net: all expected physical devices present 2023-02-28 09:21:42,650 - stages.py[DEBUG]: applying net config names for {'ethernets': {'ens3': {'dhcp4': True, 'set-name': 'ens3', 'match': {'macaddress': 'fa:16:3e:00:3c:33'}}}, 'version': 2} 2023-02-28 09:21:42,650 - util.py[DEBUG]: Reading from /sys/class/net/ens3/device/device (quiet=False) 2023-02-28 09:21:42,650 - util.py[DEBUG]: Read 7 bytes from /sys/class/net/ens3/device/device On ubuntu 20.04 this problem not persist. 2023-02-27 14:36:40,755 - util.py[DEBUG]: Reading from /sys/class/net/lo/type (quiet=False) 2023-02-27 14:36:40,755 - util.py[DEBUG]: Read 4 bytes from /sys/class/net/lo/type 2023-02-27 14:36:40,755 - networking.py[DEBUG]: net: all expected physical devices present 2023-02-27 14:36:40,755 - stages.py[DEBUG]: applying net config names for {'version': 1, 'config': [{'type': 'physical', 'mtu': 1500, 'accept-ra': False, 'subnets': [{'type': 'dhcp4'}, {'type': 'static6', 'netmask': 'ffff:ffff:ffff:ffff::', 'routes': [{'network': '::', 'netmask': '::', 'gateway': '2a10:c941:12:1::1'}], 'address': '2a10:c941:12:1::10f', 'ipv6': True}], 'mac_address': 'fa:16:3e:f3:d9:ad', 'name': 'ens3'}, {'type': 'nameserver', 'address': '8.8.8.8'}, {'type': 'nameserver', 'address': '1.1.1.1'}]} 2023-02-27 14:36:40,756 - util.py[DEBUG]: Reading from /sys/class/net/ens3/device/device (quiet=False) 2023-02-27 14:36:40,756 - util.py[DEBUG]: Read 7 bytes from /sys/class/net/ens3/device/device cloud-init version: 22.4.2-0ubuntu0~18.04.1 we tried and older version but it work same ** Affects: cloud-init Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
