Parallels has released in the recent updates of Parallels Server 5/6
new addition to his image format. Images with signature WithouFreSpacExt
have offsets in the catalog coded not as offsets in sectors (multiple
of 512 bytes) but offsets coded in blocks (i.e. header->tracks * 512)
In this case to code the virtual disk size for such images nb_sectors
field is extended to 64 bits. The reader of older images with signature
WithoutFreeSpace must manually zero most valuable bits of nb_sectors
on open.
Changes from v1:
- fixed message in patch 1
- added braces to conform qemu coding style in patches 3 & 4
- added check for ph.tracks in patch 4 to avoid offset overflow as suggested
