Bug Description
WIth the introduction of support for the VHDX in the Hyper-V driver, the following bug related to the VHD format must be taken into consideration for VHDX as well: https:/
The file structure of a VHDX file differs radically from VHD, so it make sense to file a separate bug.

Fixes Hyper-V VHDX snapshot bigger than instance
In Hyper-V, the deployed images will be extended having their
metadata size added to their base image size. This may lead to
snapshots bigger than the flavor size.
This patch adds support to the V2 utils module, so that the
maximum internal size of a requested image may be calculated
in a similar way it is done in the V1 module.
