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.
GNOME Boxes was initially introduced as beta software in GNOME 3.3 (development branch for 3.4) as of Dec 2011, [5] and as a preview release in GNOME 3.4. [6] Its primary functions were as a virtual machine manager, remote desktop client (over VNC), and remote filesystem browser, utilizing the libvirt, libvirt-glib, and libosinfo technologies. [7]
Kernel-based Virtual Machine (KVM) is a free and open-source virtualization module in the Linux kernel that allows the kernel to function as a hypervisor.It was merged into the mainline Linux kernel in version 2.6.20, which was released on February 5, 2007. [1]
VirtualBox also contains a dynamic recompiler, based on QEMU to recompile any real mode or protected mode code entirely (e.g. BIOS code, a DOS guest, or any operating system startup). [ 42 ] Using these techniques, VirtualBox could achieve performance comparable to that of VMware in its later versions.
Many guest operating systems can be run using the emulator including DOS, several versions of Linux, Xenix, Microsoft Windows, BSDs and Rhapsody OS (precursor of Mac OS X Public Beta). Bochs runs on many host operating systems, including Android OS , Linux , macOS , PlayStation 2 , Windows , and Windows CE along with its derivatives .
Some other products such as VMware and Virtual PC use similar approaches to Bochs and QEMU, however they use a number of advanced techniques to shortcut most of the calls directly to the CPU (similar to the process that JIT compiler uses) to bring the speed to near native in most cases.
Kimchi is a web management tool to manage Kernel-based Virtual Machine (KVM) infrastructure. Developed with HTML5, Kimchi is developed to intuitively manage KVM guests, create storage pools, manage network interfaces (bridges, VLANs, NAT), and perform other related tasks.
