Comment 1 Zane Bitter 2021-06-23 20:30:34 UTC

Behaviour of the dracut networking changed in RHCOS 4.6:

https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/issues/729

As a result, we need to explicitly pass ip=dhcp or ip=dhcp6 on the command line for dual-stack clusters, otherwise it will just pick the first address family for which it can get an address, to the exclusion of the other.

@zbitter 4.6 is back when cbo didn't even deploy bmo. I assume we would need to patch mao?

This issue was fixed in 4.8 and given the lack of activity here, it seems we don't need the backports. Please reopen if the backport to OCP 4.6.z is in fact needed.
