One of the side-effects of the new packaging plan is that CloudMonkey may not be installed with the RPMs, but instead require that admins use PIP to grab CloudMonkey.
Mice Xia proposed merging the VM Snapshot branch to master ahead of the 4.1 branching/feature freeze on January 28th. However, there were a number of questions about the feature's implementation and consensus was not reached in time for the 4.1 branch's creation.
On the plus side, this is why we have time-based releases. While it will delay inclusion into CloudStack slightly, the feature will be well-poised to go into 4.2 and the additional attention that the discussion has raised will likely make it that much better a feature when merged to master. It also means that a single feature won't delay the 4.1 release, which already has quite a lot of improvements and new features that CloudStack users will want to have ready when it's scheduled for release.
