Feature pages are design documents that developers have created while collaborating on oVirt.

Most of them are outdated, but provide historical design context.

They are not user documentation and should not be treated as such.

Detailed Description

The feature provides administration and management functionalities for floating disks. A floating disk should behave as a flexible independent entity that can be attached to any VM. Any virtual disk can be in a floating state - by unattaching the disk from the VM/s.

Benefit to oVirt

The feature introduces a significant improvement to oVirt compatibility and flexabilty regarding disks usage. Supporting a floating state for disks is essential to derived features (e.g. ‘Shared RAW Disk’ and ‘Direct LUN Disk’) and dependent implementations (e.g. application clustering, shared data warehouse).

Affected oVirt projects:

  • API
  • CLI
  • Engine-core
  • Webadmin
  • User Portal
