      2025-10-15: Doc PRs almost ready, descheduler operator and ACM releases are on-track (although async - days - from the CNV release). Dashboard testing still in progress but it will be shipped only with ACM v2.15 in November...

      Goal

      This is a follow up from epic CNV-51099 to be able to ship our load aware balancing solution as GA.
      Remaining work includes:

      • a dashboard to help the cluster admin monitor load aware balancing
      • cluster admin visible alerts when the descheduler or its dependencies are not properly configured
      • a mechanism to let a VM owner opt-in/opt-out for the single VM without the need to reboot it

      User Stories

      • As a cluster administrator, I want have a dedicated dashboard to monitor load aware balancing, so that I can monitor if my cluster is balanced and how the load aware balancing is working
      • As a cluster administrator, I want to receive an alert if load aware balancing is not properly configured for my cluster
      • As a VM owner, I want have an opt-in/opt-out mechanism for my VM, so that I can can easily opt-in/opt-out without the need to reboot my VM (setting an higher priority is also an option but it currently requires a reboot)

      Non-Requirements

      • UI work is tracked on a different epic: CNV-52012
