H A Dimages.rst6 QEMU supports many disk image formats, including growable disk images
8 encrypted disk images.
12 Quick start for disk image creation
15 You can create a disk image with the command::
19 where myimage.img is the disk image filename and mysize is its size in
30 If you use the option ``-snapshot``, all disk images are considered as
33 disk images by using the ``commit`` monitor command (or C-a s in the
44 writable block device using the ``qcow2`` disk image format. Normally
64 ``info snapshots``) and a snapshot of every writable disk image. The VM
66 block device. The disk image snapshots are stored in every disk image.
