In addition to the formats we've already reviewed, QEMU has varying levels of support for several other disk image formats. See the documentation[42] for a complete description of their supported options.
The following formats are supported by QEMU in a read-write mode:
Old QEMU image format with support for backing files and compact image files (when your filesystem or transport medium does not support holes).
User Mode Linux Copy On Write image format. It is supported only for compatibility with previous versions.
VirtualBox 1.1 compatible image format.
VMware 3 and 4 compatible image format.
VirtualPC compatible image format (VHD).
The following formats are also supported by QEMU in a read-only mode:
Bochs images of growing type.
Linux Compressed Loop image, useful only to reuse directly compressed CD-ROM images present for example in the Knoppix CD-ROMs[43].
Apple disk image.
Parallels disk image format.
