[Qemu-devel] [PATCH 0/4] VHD/VPC format compatibility |

This is a long-standing issue that has come up many times, and has had
several different patches posted to fix it. Virtual PC, and Hyper-V
calculate the disk geometry differently for VHD, leading to compatibility
issues.
We want to fix these compatibility problems, however we want to make sure
we do not break backwards compatibility.
There are two areas of compatibility addressed:
* Reading images (Patch 1)
* Creating images (Patch 3)
Please see the commit messages in Patches 1,3 for details.
Jeff Cody (4):
block/vpc: choose size calculation method based on creator_app field
block/vpc: tests for auto-detecting VPC and Hyper-V VHD images
block/vpc: give option to force the current_size field in .bdrv_create
block/vpc: add tests for image creation force_size parameter
