Current status

• Targeted release: Fedora 20
• Last updated: 2013-06-11
• Tracker bug: <will be assigned by the Wrangler>

Detailed Description

qemu and libvirt have all the major pieces in place for performing safe VM snapshots/checkpoints, however there isn't any simple discoverable UI. This feature will track adding that UI to virt-manager, and any other virt stack bits that need to be fixed/improved. This includes adding functionality to libvirt to support deleting and rebasing to external snapshots.

Benefit to Fedora

• Making snapshots easier to use means more QA folks and packagers will use them, makes their lives easier.
• End users have been asking it for a while, gives them incentive to update or make the jump to Fedora.

Scope

• Proposal owners:

1. Verify that all the libvirt APIs are fully implemented, some pieces were missing at last check.
2. Implement virt-manager UI
