Virtio Driver List Rating: 7,4/10 7249 reviews

This repository contains KVM/QEMU Windows guest drivers, for bothparavirtual and emulated hardware. The code builds and ships as partof the virtio-win RPM on Fedora and Red Hat Enterprise Linux, and thebinaries are also available in the form of distribution-neutral ISOand VFD images. If all you want is use virtio-win in your Windowsvirtual machines, go to theFedora virtIO-win documentationfor information on obtaining the binaries.

Download and install the virtio-win package on the host with the yum command. # yum install virtio-win The list of virtio-win packages that are supported on Windows operating systems, and the current certified package version, can be found here.

Virtio adopts a frontend-backend architecture that enables a simple but flexible framework for both frontend and backend virtio drivers. The FE driver merely needs to offer services configure the interface, pass messages, produce requests, and kick backend virtio driver. As a result, the FE driver is easy to implement and the performance.

If you'd like to build virtio-win from sources, clone this repo andfollow the instructions in Building the Drivers.Note that the drivers you build will be either unsigned or test-signedwith Tools/VirtIOTestCert.cer, which means that Windows will not loadthem by default. See Microsoft's driver signing pagefor more information on test-signing.

If you want to build cross-signed binaries (like the ones that ship inthe Fedora RPM), you'll need your own code-signing certificate.Cross-signed drivers can be used on all versions of Windows except forthe latest Windows 10 with secure boot enabled. However, systems withcross-signed drivers will not receive Microsoft support.

If you want to produce Microsoft-signed binaries (fully supported,like the ones that ship in the Red Hat Enterprise Linux RPM), you'llneed to submit the drivers to Microsoft along with a set of testresults (so called WHQL process). If you decide to WHQL the drivers,make sure to base them on commit eb2996de or newer, since the GPLlicense used prior to this commit is not compatible with WHQL.Additionally, we ask that you make a change to the Hardware IDs sothat your drivers will not match devices exposed by the upstreamversions of KVM/QEMU. This is especially important if you plan todistribute the drivers with Windows Update, see theMicrosoft publishing restrictions for more details.

Kernel-based Virtual Machine (KVM) is a virtualization module in the Linux kernel that allows the kernel to function as a hypervisor. It was merged into the Linux kernel mainline in kernel version 2.6.20, which was released on February 5, 2007.[1] KVM requires a processor with hardware virtualization extensions, such as Intel VT or AMD-V.[2] KVM has also been ported to other operating systems such as FreeBSD[3] and illumos[4] in the form of loadable kernel modules.

KVM was originally designed for x86 processors and has since been ported to S/390,[5]PowerPC,[6]IA-64, and ARM.[7]

KVM provides hardware-assisted virtualization for a wide variety of guest operating systems including Linux, BSD, Solaris, Windows, Haiku, ReactOS, Plan 9, AROS Research Operating System[8] and macOS.[9] In addition, Android 2.2, GNU/Hurd[10] (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.[11]

Additionally, KVM provides paravirtualization support for Linux, OpenBSD,[12] FreeBSD,[13] NetBSD,[14] Plan 9[15] and Windows guests using the VirtIO[16] API. This includes a paravirtual Ethernet card, disk I/O controller,[17] balloon device, and a VGA graphics interface using SPICE or VMware drivers.

History[edit]

Avi Kivity began the development of KVM at Qumranet, a technology startup company[18] that was acquired by Red Hat in 2008.[19]

KVM surfaced in October, 2006[20] and was merged into the Linux kernel mainline in kernel version 2.6.20, which was released on 5 February 2007.[1]

KVM is maintained by Paolo Bonzini.[21]

Internals[edit]

KVM provides device abstraction but no processor emulation. It exposes the /dev/kvm interface, which a user mode host can then use to:

  • Set up the guest VM's address space. The host must also supply a firmware image (usually a custom BIOS when emulating PCs) that the guest can use to bootstrap into its main OS.
  • Feed the guest simulated I/O.
  • Map the guest's video display back onto the system host.

On Linux, QEMU versions 0.10.1 and later is one such userspace host. QEMU uses KVM when available to virtualize guests at near-native speeds, but otherwise falls back to software-only emulation.

Internally, KVM uses SeaBIOS as an open source implementation of a 16-bit x86 BIOS.[23]

Features[edit]

KVM support hot plug vCPUs[24], dynamic memory management[25] and Live Migration since February 2007[26][27] among other features.

Graphical management tools[edit]

libvirt supports KVM
  • Kimchi – web-based virtualization management tool for KVM
  • Virtual Machine Manager – supports creating, editing, starting, and stopping KVM-based virtual machines, as well as live or cold drag-and-drop migration of VMs between hosts.
  • Proxmox Virtual Environment – an open-source virtualization management package including KVM and LXC. It has a bare-metal installer, a web-based remote management GUI, a HA cluster stack, unified storage, flexible network, and optional commercial support.
