12.7. Glance Image Storage Domains
12.7.1. Glance Image Storage Domains
Storage domains with type set to
Image
represent instances of an OpenStack image service that has been added to the Red Hat Enterprise Virtualization environment as an external provider. These Glance image storage domains contain an images
sub-collection with virtual machine images that have been exported to or can be imported from that Glance image storage domain.
Example 12.12. Listing the images sub-collection of a Glance image storage domain

The
import
action imports a virtual machine image from a Glance image storage domain. The destination storage domain is specified with a storage_domain
reference, and the destination cluster with a cluster
reference.
Include an optional
name
element to give the virtual machine or template a specific name.
Example 12.13. Action to import a virtual machine from a Glance image storage domain
POST /api/storagedomains/00000000-0000-0000-000000000000/images/ 00000000-0000-0000-000000000000/import HTTP/1.1 Accept: application/xml Content-type: application/xml <action> <storage_domain> <name>images0</name> </storage_domain> <cluster> <name>images0</name> </cluster> </action>
You can also import images as templates by specifying the
import_as_template
reference:
Example 12.14. Action to import a virtual machine from a Glance image storage domain as a template
POST /api/storagedomains/00000000-0000-0000-000000000000/images/ 00000000-0000-0000-000000000000/import HTTP/1.1 Accept: application/xml Content-type: application/xml <action> <storage_domain> <name>images0</name> </storage_domain> <cluster> <name>images0</name> </cluster> </import_as_template>true</import_as_template> </action>
