12.6. Export Storage Domains

12.6.1. Export Storage Domains

Note

The export storage domain is deprecated. Storage data domains can be unattached from a data center and imported to another data center in the same environment, or in a different environment. Virtual machines, floating virtual disk images, and templates can then be uploaded from the imported storage domain to the attached data center. See the Importing Existing Storage Domains section in the Red Hat Virtualization Administration Guide for information on importing storage domains.
Storage domains with type set to export contain vms and templates sub-collections, which list the import candidate VMs and templates stored on that particular storage domain.

Example 12.6. Listing the virtual machines sub-collection of an export storage domain

VMs and templates in these collections have a similar representation to their counterparts in the top-level VMs and templates collection, except they also contain a storage_domain reference and an import action.
The import action imports a virtual machine or a template from an export storage domain. The destination cluster and storage domain is specified with cluster and storage_domain references.
Include an optional name element to give the virtual machine or template a specific name.

Example 12.7. Action to import a virtual machine from an export storage domain

Example 12.8. Action to import a template from an export storage domain

</action>
Include an optional clone Boolean element to import the virtual machine as a new entity.

Example 12.9. Action to import a virtual machine as a new entity
