      SUMMARY

      Some workloads are going to require the ability to do memory hotplug, especially compute intensive tasks.

      USER STORIES

      • As VM owner i would like to add additional compute power to my VM so that i could give extra processing power during an end of the month/year periods

      OWNERS

      Role Contact
      PM TBD
      Documentation Owner TBD
      Delivery Owner (See assignee)
      Quality Engineer (See QA contact)

      NOTES

      There are some potential issues that need to be sorted out.

      • Kubernetes scheduling needs to be aware of increased memory requirements of a pod.
      • We need a consistent API to follow for hotplug in general

      Goals:

      • Additional memory could be added from admin console
      • Additional memory could be added from CLI console
      • In the case adding memory is failing a proper error message with the reason/next steps should be populated to the user
