A variant of IMG, called IMZ, consists of a gzipped version of a raw floppy disk image. These files use the .imz file extension, and are commonly found in compressed images of floppy disks created by WinImage. QEMU uses the .img file extension for raw images of hard drive disks, calling the format simply "raw".
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.
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.
Mtools is an open source collection of utilities to allow a Unix operating system to manipulate files on an MS-DOS file system, typically a floppy disk or floppy disk image. [2] [3] The mtools are part of the GNU Project and are released under the GNU General Public License (GPL-3.0-or-later).
A typical floppy disk controller sends an MFM / FM / GCR encoded signal to the drive to write data, and expects a similar signal returned when reading the drive. [6] On a write, a hardware PLL or a software-based filter component undoes the encoding, and stores the sector data as logically written by the host.
Further, there are less issues with wear and tear. A hard disk drive or solid-state drive in a virtual machine is implemented as a disk image (i.e. either the VHD format used by Microsoft's Hyper-V, the VDI format used by Oracle Corporation's VirtualBox, the VMDK format used for VMware virtual machines, or the QCOW format used by QEMU).

KryoFlux consists of a small hardware device, [4] [5] which is a software-programmable FDC system that runs on small ARM-based devices that connects to a floppy disk drive and a host PC over USB, and software for accessing the device. KryoFlux reads "flux transitions" from floppy disks at a very fine resolution. [6]
"*It isn't possible to boot from the USB subsystem from within QEMU (it only can boot from floppy, hard disk, CD-ROM or an image of any of these (eg: an ISO Image of Windows XP Installation CD)), although a USB driver is available with the "-usb" switch, and will soon be loaded by default."
