[Qemu-devel] [PATCH v2 00/12] Adding VMDK monolithic flat support

[famcool@gmail.com]

From: Fam Zheng <famcool@gmail.com>

VMDK multiple file images can not be recognized for now. This patch series is
adding monolithic flat support to it, that is the image type with two
files, one text descriptor file and a plain data file. This type of
image can be created in VMWare, with the options "allocate all disk
space now" and "store virtual disk as a single file" checked.

A VmdkExtent structure is introduced to hold the image "extent"
information, which makes further adding multi extents support of VMDK
easy. An image creating option "flat" is added for creating flat
(preallocated) image.

Fam Zheng (12):
  VMDK: introduce VmdkExtent
  VMDK: bugfix, align offset to cluster in get_whole_cluster
  VMDK: probe for monolithicFlat images
  VMDK: separate vmdk_open by format version
  VMDK: add field BDRVVmdkState.desc_offset
  VMDK: flush multiple extents
  VMDK: move 'static' cid_update flag to bs field
  VMDK: change get_cluster_offset return type
  VMDK: open/read/write for monolithicFlat image
  VMDK: create different subformats
  VMDK: fix coding style
  BlockDriver: add bdrv_get_allocated_file_size() operation
