Image

An Image represents a bootable virtual machine template managed by the Glance service. Images serve as the foundation for launching instances and define the base operating system and file system for virtual machines.

Key functions of the Image service :

• Boot Source: Provides the base OS image for VM instances.

• Centralized Image Repository: Allows users to upload, manage, and version OS templates.

• Visibility Control: Supports private, public, and shared visibility modes.

• Multi-Backend Support: Stores images in various backends such as Ceph RBD, NFS, Swift, or the local filesystem.

📄️ Upload image

Use the Skyline UI to upload an image file (e.g., .qcow2, .raw, .iso) into Glance.

📄️ Import image(CLI)

When using the Image Import workflow, image uploads follow a staged process.

📄️ Migrate image

Image migration from VMware or Hyper-V to CubeCOS involves converting virtual machine images into a format compatible with CubeCOS, and uploading them to the Glance image service.
