33.3. Using qemu-img
The qemu-img command line tool is used for formatting various file systems used by Xen and KVM.
qemu-img should be used for formatting guest images, additional storage devices and network
storage. qemu-img options and usages are listed below.
Format t in g an d creat in g n ew imag es o r devices
Create the new disk image filename of size size and format format.
# qemu-img create [-6] [-e] [-b base_image] [-f format] filename [size]
If base_image is specified, then the image will record only the differences from base_image. No size
needs to be specified in this case. base_image will never be modified unless you use the "commit"
monitor command.
Co n vert an exist in g imag e t o ano t her f o rmat
The convert option is used for converting a recognized format to another image format.
