Default quotas driver used by quantum is - <filename>quantum.quota.ConfDriver</filename>, all limits set in <filename>/etc/quantum/ <title>Allow subnet ip-range overlapping</title>

changed to - <filename>quantum.db.quota_db.DbQuotaDrive</filename>. When deploying environments, Murano will create dedicated network for each of them, and every such network will have a subnet created.
</para> All these subnets will have identical ip-ranges. Theoretically this is perfectly fine, as these subnets belong to different isolated Networks
