The patchset implements additional compatibility bits for Parallels
format:
- initial support of parsing of Parallels DiskDeskriptor.xml
Typically Parallels disk bundle consists of several images which are
glued by XML disk descriptor. Also XML hides inside several important
parameters which are not available in the image header.
- support for padded Parallels images.
For the time being Parallels was created an optimization for such OSes
in its desktop product. Desktop users are not qualified enough to create
properly aligned installations. Thus Parallels makes a blind guess
on a customer behalf and creates so-called "padded" images if guest
OS type is specified as WinXP, Win2k and Win2k3.
The code uses approach from VMDK support, either image or XML descriptor
could be used. Though there is temporary hack in the opening code:
BlockDriverState->file is being reopened inside parallels_open. I prefer
to keep this code in this state till proper Parallels snapshots support
in order to minimize current changes.
Changes from v1:
- dropped already merged part (original patches 1-3)
