Supported image file formats:

raw 
Raw disk image format (default). This format has the advantage of being simple and easily exportable to all other emulators. If your file system supports holes (for example in ext2 or ext3 on Linux or NTFS on Windows), then only the written sectors will reserve space. Use "qemu-img info" to know the real size used by the image or "ls -ls" on Unix/Linux.

qcow2
QEMU image format, the most versatile format. Use it to have smaller images (useful if your filesystem does not supports holes, for example on Windows), optional AES encryption, zlib based compression and support of multiple VM snapshots.

   Supported options:
   "backing_file"
     File name of a base image (see create subcommand)
   "backing_fmt"
     Image format of the base image
   "encryption"
     If this option is set to "on", the image is encrypted.

Encryption uses the AES format which is very secure (128 bit keys). Use a long password (16 characters) to get maximum protection.

   "cluster_size"
    Changes the qcow2 cluster size (must be between 512 and 2M). Smaller cluster sizes can improve the image file size whereas larger cluster sizes generally provide better performance.
    "preallocation"
      Preallocation mode (allowed values: off, metadata). An image with preallocated metadata is initially larger but can improve performance when the image needs to grow.


qcow
Old QEMU image format. Left for compatibility.

   Supported options:
    "backing_file"
      File name of a base image (see create subcommand)
    "encryption"
      If this option is set to "on", the image is encrypted.

cow User Mode Linux Copy On Write image format. Used to be the only growable image format in QEMU. It is supported only for compatibility with previous versions. It does not work on win32.

vdi 
VirtualBox 1.1 compatible image format.


vmdk
VMware 3 and 4 compatible image format.

       Supported options:

           "backing_fmt"
               Image format of the base image

           "compat6"
               Create a VMDK version 6 image (instead of version 4)


vpc 
VirtualPC compatible image format (VHD).


cloop
Linux Compressed Loop image, useful only to reuse directly compressed CD-ROM images present for example in the Knoppix CD-ROMs.
