qcow is a file format for disk image files used by QEMU, a hosted virtual machine monitor. [1] It stands for "QEMU Copy On Write" and uses a disk storage optimization strategy that delays allocation of storage until it is actually needed.
QEMU integrates several services to allow the host and guest systems to communicate for example: an integrated SMB server and network-port redirection (to allow incoming connections to the virtual machine). It can also boot Linux kernels without a bootloader. QEMU does not depend on the presence of graphical output methods on the host system.
Programs such as dsktrans from the LibDsk [2] suite of command-line tools (available for Linux, MS-DOS, and Microsoft Windows) will convert between different raw disk image formats. dd can be used in Unix to create raw disk image files of disks. QEMU uses IMG files as its default format for hard drive disk images.

EXIF – Exchangeable image file format (Exif) is a specification for the image format used by digital cameras GIF – CompuServe 's Graphics Interchange Format GIFV – Graphics Interchange Format Video, a format used for short, looping videos that combines the advantages of GIFs and videos, with better playback quality and lower file sizes [ 14 ]
Fabrice Bellard (French pronunciation: [fa.bʁis bɛ.laʁ]; born 1972) is a French computer programmer known for writing FFmpeg, QEMU, and the Tiny C Compiler.He developed Bellard's formula for calculating single digits of pi.
A flat image allocates space ahead of time while a sparse image grows as the virtual machine writes to it. Flat images can use the underlying file system's sparse file capability, as is done with the vmfs format on ESXi. An image can also refer to a parent image and only store changes made in a copy-on-write fashion. This enables creating a ...
In computer science, dynamic recompilation is a feature of some emulators and virtual machines, where the system may recompile some part of a program during execution. By compiling during execution, the system can tailor the generated code to reflect the program's run-time environment, and potentially produce more efficient code by exploiting information that is not available to a traditional ...
