Before you can create virtual machines, you must provision and attach storage to a data center. You can use Network File System (NFS), Internet Small Computer System Interface (iSCSI), Fibre Channel Protocol (FCP), or Gluster storage. You can also configure local storage attached directly to hosts.

Storage devices in Oracle Linux Virtualization Manager are referred to as data domains, which are used to store virtual hard disks, snapshots, ISO files, and templates. Every data center must have at least one data domain. Data domains cannot be shared between data centers.
