Red Hat Enterprise Virtualization has an explicit permissions to allow or deny snapshot creation. This permission is evaded and unchecked during live storage migration of a vm between hosts. Long chains of snapshots may cause a performance degradation to the VM. Effectively a user who can live migrate a host, could prevent the host from starting if migrated frequently. Acknowledgements: This issue was discovered by Red Hat Enterprise Visualization Engineering.
