3.14. Example: Attach ISO Image to Virtual Machine
The boot media for our example virtual machine requires an CD-ROM or DVD ISO image for an operating system installation. This example uses a Red Hat Enterprise Server 6 ISO image for installation.
ISO images must be available in the
iso1 ISO domain for the virtual machines to use. Red Hat Virtualization Platform provides an uploader tool that ensures that the ISO images are uploaded into the correct directory path with the correct user permissions.
Once the ISO is uploaded, an API user requests the ISO storage domain's
files sub-collection to view the file resource:
Example 3.16. View the files sub-collection in an ISO storage domain
Request:
GET /ovirt-engine/api/storagedomains/00f0d9ce-da15-4b9e-9e3e-3c898fa8b6da/files HTTP/1.1
Accept: application/xml
cURL command:
# curl -X GET -H "Accept: application/xml" -u [USER:PASS] --cacert [CERT] \
https://[RHEVM Host]:443/ovirt-engine/api/storagedomains/00f0d9ce-da15-4b9e-9e3e-3c898fa8b6da/files
The API returns the following representation of the files sub-collection:
<files>
<file id="rhel-server-6.0-x86_64-dvd.iso"
href="/ovirt-engine/api/storagedomains/00f0d9ce-da15-4b9e-9e3e-3c898fa8b6da/
files/rhel-server-6.0-x86_64-dvd.iso.iso">
<name>rhel-server-6.0-x86_64-dvd.iso.iso</name>
<storage_domain id="00f0d9ce-da15-4b9e-9e3e-3c898fa8b6da"
href="/ovirt-engine/api/storagedomains/00f0d9ce-da15-4b9e-9e3e-3c898fa8b6da"/>
</file>
</files>
An API user attaches the
rhel-server-6.0-x86_64-dvd.iso to our example virtual machine. Attaching an ISO image is equivalent to using the Change CD button in the Administration or User Portal.
