Change subject: core, restapi: Introducing support for attaching disk snapshot ...................................................................... core, restapi: Introducing support for attaching disk snapshot This patch adds the engine support for attaching a disk snapshot to a VM (currently different VM than the one for which the VM snapshot was taken). Before this change, when attaching a disk to a vm only the active volume was used, if the user wanted to see the disk content at some snapshot he had to preview that snapshot. After this change, a snapshot of a disk can be attached to another vm, regardless of the disk not being marked as shareable - when doing so, VDSM should create a temp snapshot allowing read/write access above the selected snapshot, the above should happen when hotplugging a disk/ running a vm. The following limitations currently applies on that ability: 1. The created temp snapshots is stored on the host local storage (the host that the vm is running on) and not on the shared storage (domains) therefore the vm can't be migrated. 2. A disk snapshot can be attached to a different VM than the one of which the snapshot (VM snapshot) was taken of. Usage: 1. Navigate to the wanted disk snapshot from REST by accessing: SERVER:PORT:/api/vms/GUID/snapshots/GUID/disks 2. POST the copied disk XML to: http://SERVER:PORT/api/vms/GUID/disks/ Patch with lock handling is dependent on this one to ease the review. OPEN ISSUES: UI - would be handled in a following patch (the information is accessible through REST) Change-Id: I02579bf1a91cd294a5040acf432f1fdb87eb18c1 Signed-off-by: Liron Aravot
