QEMU can be used with a Kernel-based Virtual Machine (KVM) to emulate hardware at near-native speeds. Additionally, it supports user-level processes, allowing applications compiled for one processor architecture to run on another. [4] QEMU supports the emulation of x86, ARM, PowerPC, RISC-V, and other architectures.
Supported drivers for Windows 2000, Windows 2003, Windows 2008, Windows XP, Windows Vista, FreeBSD, Linux (SUSE 10 released, more announced) Proprietary: Hyper-V (2012+) Microsoft: x86-64 with Intel VT-x or AMD-V, ARMv8 [4] x86-64, (up to 64 physical CPUs), ARMv8 Windows 8, 8.1, 10, and Windows Server 2012 w/Hyper-V role, Microsoft Hyper-V Server
Additionally, KVM provides paravirtualization support for Linux, OpenBSD, [14] FreeBSD, [15] NetBSD, [16] Plan 9 [17] and Windows guests using the VirtIO API. [18] This includes a paravirtual Ethernet card , disk I/O controller, [ 19 ] balloon driver , and a VGA graphics interface using SPICE or VMware drivers.
The X.Org Server driver for the QXL framebuffer device includes a wrapper script, [12] which makes it possible to launch a Xorg server whose display is exported via the SPICE protocol. This enables use of SPICE in a remote desktop environment, without requiring QEMU/KVM virtualization. virt-viewer
The primary driver was the potential for server consolidation: virtualization allowed a single server to cost-efficiently consolidate compute power on multiple underutilized dedicated servers. The most visible hallmark of a return to the roots of computing is cloud computing , which is a synonym for data center based computing (or mainframe ...
The Universal TUN/TAP Driver originated in 2000 as a merger of the corresponding drivers in Solaris, ... QEMU/KVM; User-mode Linux ... Windows 2000/XP/Vista/7/8/8.1 ...
SeaBIOS also runs inside an emulator; it is the default BIOS for the QEMU and KVM virtualization environments, and can be used with the Bochs emulator. It is also included in some Chromebooks , although it is not used by ChromeOS .
