As an hardening measure (principle of least privilege), the right of creating, editing and deleting VirtualMachineInstanceMigrations are not anymore assigned by default to namespace admins.The new kubevirt.io:migrate clusterrole can be bound by cluster admins to the users that need tocontinue directly managing live migrations with something like: kubectl create rolebinding kvmigrate --clusterrole=kubevirt.io:migrate --user=user1 --user=user2 --group=group1kubectl label --overwrite clusterrole kubevirt.io:migrate rbac.authorization.k8s.io/aggregate-to-admin=true can be used by a clusteradmin as an escape hatch to restore the previous behavior. |
