}}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.WEB KVM was originally designed for x86 processors but has since been ported to ESA/390,WEB,article.gmane.org/gmane.comp.emulators.kvm.devel/2570, Gmane - Mail To News And Back Again, 2007-05-07,article.gmane.org/gmane.comp.emulators.kvm.devel/2570," title="web.archive.org/web/20070929124348article.gmane.org/gmane.comp.emulators.kvm.devel/2570,">web.archive.org/web/20070929124348article.gmane.org/gmane.comp.emulators.kvm.devel/2570, 2007-09-29, dead, PowerPC,Gmane Loom {{webarchive|url=https://web.archive.org/web/20070929103042news.gmane.org/gmane.comp.emulators.kvm.devel/2595 |date=2007-09-29 }} IA-64, and ARM.WEB,columbia.github.com/linux-kvm-arm, KVM/ARM Open Source Project, 2017-11-01,columbia.github.com/linux-kvm-arm/," title="web.archive.org/web/20130310052146columbia.github.com/linux-kvm-arm/,">web.archive.org/web/20130310052146columbia.github.com/linux-kvm-arm/, 2013-03-10, dead, The IA-64 port was removed in 2014.WEB,git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=003f7de6258900e17f6206e8e417d76c75ca549f, kernel/git/torvalds/linux.git: KVM: ia64: remove, KVM supports hardware-assisted virtualization for a wide variety of guest operating systems including BSD, Solaris, Windows, Haiku, ReactOS, Plan 9, AROS, macOS, and even other Linux systems.WEB,www.linux-kvm.org/page/Guest_Support_Status, KVM wiki: Guest support status, 2007-05-27, WEB,www.contrib.andrew.cmu.edu/~somlo/OSXKVM/, Running Mac OS X as a QEMU/KVM Guest, 2014-08-20, In addition, Android 2.2, GNU/HurdWEB,www.gnu.org/software/hurd/hurd/status.html, status, Gnu.org, 2014-02-12, (Debian K16), Minix 3.1.2a, Solaris 10 U3 and Darwin 8.0.1, together with other operating systems and some newer versions of these listed, are known to work with certain limitations.WEB,www.linux-kvm.org/page/Guest_Support_Status, Guest Support Status - KVM, Linux-kvm.org, 2014-02-12, Additionally, KVM provides paravirtualization support for Linux, OpenBSD,WEB,man.openbsd.org/virtio.4, OpenBSD man page virtio(4), 2018-02-04, FreeBSD,WEB,people.freebsd.org/~kuriyama/virtio/, virtio binary packages for FreeBSD, 2012-10-29, NetBSD,WEB,netbsd.gw.com/cgi-bin/man-cgi?virtio++NetBSD-current, NetBSD man page virtio(4), 2013-07-15, 2019-11-13,web.archive.org/web/20191113035952/https://netbsd.gw.com/cgi-bin/man-cgi?virtio++NetBSD-current, dead, Plan 9WEB,code.google.com/p/plan9front/wiki/qemu, plan9front, 2013-02-11, and Windows guests using the VirtIO API.WEB,lwn.net/Articles/239238/, An API for virtual I/O: virtio, 2007-07-11, 2014-04-16, LWN.net, This includes a paravirtual Ethernet card, disk I/O controller,WEB,linux-iscsi.org/wiki/vHost, SCSI target for KVM wiki, linux-iscsi.org, 2012-08-07, 2012-08-12, 2020-06-05,linux-iscsi.org/wiki/VHost," title="web.archive.org/web/20200605120413linux-iscsi.org/wiki/VHost,">web.archive.org/web/20200605120413linux-iscsi.org/wiki/VHost, dead, balloon driver, and a VGA graphics interface using SPICE or VMware drivers.
