- qcow stands for "QEMU Copy On Write" and denotes a disk storage optimization strategy that delays allocation of storage until it is actually needed. QEMU is an emulator and virtual machine container, and it can use a variety of virtual disk images which are generally associated with specific guests operating systems. The set of possible disk image formats have commonly accepted short names: vvfat - Virtual VFAT vpc - Windows Virtual PC bochs - Bochs file system dmg - Macintosh disk image cloop - Linux compressed loop vmdk - VMware virtual machine disk format qcow - QEMU Copy-on-write qcow2 - QEMU Copy-on-write (new in version 0.9) raw - Raw file system (no special format) cow - User-mode Linux copy-on-write
- qcow è un tipo di immagine disco che può essere usato con l'emulatore QEMU in alternativa a vvfat, vpc, bochs, dmg, cloop, vmdk, cow, e raw, a seconda del Sistema Operativo. Un'immagine in formato qcow cresce mano a mano che si aggiungono dati, e supporta lo standard di crittografia AES e la decompressione transparente. Secondo le QEMU FAQ, che fa riferimento a sua volta a DmUserspace, un'immagine qcow può essere montata direttamente in Linux.
- Qcow2 — это формат дискового образа программы QEMU. Название является аббревиатурой названия формата Copy-On-Write. QEMU может использовать базовый образ, который доступен только для чтения, а запись производить в образ qcow2. Среди поддерживаемых форматов QEMU, этот — наиболее универсальный. Он удобен для использования маленьких образов в формате файловых систем не поддерживаемых операционной системой, а также образов, с поддержкой шифрования AES, сжатием, основанным на Zlib и поддержкой множественных снапшотов виртуальных машин.
