On a bare metal machine from Oracle Cloud using iSCSI boot in an IPv6-only environment, the initial DHCPv6 setup is performed by iPXE to boot the system. Subsequently, systemd attempts to perform its own DHCPv6 configuration, but this process fails due to a mismatch in prefix length.
Specifically, the network link remains stuck in the “configuring” state and does not transition to an active state. This occurs because systemd assumes a default prefix length of 128, while iPXE may assign a different value—64 in this case, as indicated by /sys/firmware/ibft/ethernet0/prefix-len. Unfortunately, there is no current workaround, as this inconsistency between systemd's assumption and the actual configuration leads to a persistent configuration failure. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2115418 Title: systemd-networkd-wait-online service times out in IPv6-only environments To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-images/+bug/2115418/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
