    • This will be fixed in 4.16.0 ahead of 4.17 so no 4.17 release notes necessary
    • Release Note Not Required
    • Done

      Description of problem: OCP doesn't resume from "hibernation" (shutdown/restart of cloud instances).

      NB: This is not related to certs.

      Version-Release number of selected component (if applicable): 4.16 nightlies, at least 4.16.0-0.nightly-2024-05-14-095225 through 4.16.0-0.nightly-2024-05-21-043355

      How reproducible: 100%

      Steps to Reproduce:

      1. Install 4.16 nightly on AWS. (Other platforms may be affected, don't know.)
      2. Shut down all instances. (I've done this via hive hibernation; vrutkovs@redhat.com has done it via cloud console.)
      3. Start instances. (Ditto.)

      Actual results: OCP doesn't start. Per Vadim:
      "kubelet says host IP unknown; known addresses: [] so etcd can't start."

      Expected results: OCP starts normally.

      Additional info: We originally thought this was related to OCPBUGS-30860, but reproduced with nightlies containing the updated AMIs.
