Description Andrew Dahms 2014-08-07 23:36:53 UTC

+++ This bug was initially created as a clone of Bug #1124107 +++

This change affects the method by which snapshots are deleted. Previously, deleting a snapshot was not as easy as might be expected, and involved creating a temporary space equivalent to the full size of the disk (even for thinly provisioned disks). With this change, this process has been greatly simplified.

This bug is somewhat tricky and will involve updating the section of the Technical Guide that talks about snapshot deletion. It might also involve looking into the sections of the Administration Guide and seeing whether there is any mention of the mechanism by which snapshots are deleted. However, the bulk of the work on this bug will be conceptual and centered around the Technical Guide.

What Changed
------------------------------
The following topic was revised to remove a step instructing users to shut down the virtual machine before deleting a snapshot and to add a 'note' box to emphasize that snapshots can be deleted at any time.

Peer reviewed.

The procedure no longer mentions shutting down the virtual machine, and the note box clearly states that snapshots can be deleted while a virtual machine is running.

VERIFIED.
