Goal
Live Migration does not work if there are no available resources to a user - qither due to quota or cluster capacity.
Scope of this epic is to define how KubeVirt can prevent that live migrations - which can block OCP upgrades - will not work anymore due to resource pressure.
Requirements (in order of priority) on the solution:
- Quota which also works for Pods
- Certain pods will be ignored based on rules. Rules are provided by the system/operator, or an admin
- Does not modify admin created quota
- Works with preemption
User Stories
- As a cluster admin, I want to be sure that VMs can always live migrate even when a tenant is out of quota so that cluster upgrades will pass.
Non-Requirements
- List of things not included in this epic, to alleviate any doubt raised during the grooming process.
Notes
- Any additional details or decisions made/needed
