A virtual machine image, referred to in this document simply as an image, is a single file that contains a virtual disk that has a bootable operating system installed on it. Images are used to create virtual machine instances within the cloud. For information about creating image files, see the OpenStack Virtual Machine Image Guide on the OpenStack website.
Depending on your role, you may have permission to upload and manage virtual machine images. Your Cloud Administrator might restrict the upload and management of images. If you have the appropriate privileges, you can use the dashboard to upload and manage images in the admin project.
