Introduction
VirtIO Drivers are paravirtualized drivers for kvm/Linux (see http://www.linux-kvm.org/page/Virtio). In short, they enable direct (paravirtualized) access to devices and peripherals for virtual machines using them, instead of slower, emulated, ones.
A quite extended explanation about VirtIO drivers can be found here http://www.ibm.com/developerworks/library/l-virtio.
At the moment these kind of devices are supported:
- block (disks drives), see Paravirtualized Block Drivers for Windows
- network (ethernet cards), see Paravirtualized Network Drivers for Windows
- balloon (dynamic memory management), see Dynamic Memory Management
You can maximize performances by using VirtIO drivers. The availability and status of the VirtIO drivers depends on the guest OS and platform.
Windows OS Support
Windows does not have native support for VirtIO devices included.But, there is excellent external support through opensource drivers, which are available compiled and signed for Windows:
Note that this repository provides not only the most recent, but also many older versions.Those older versions can still be useful when a Windows VM shows instability or incompatibility with a newer driver version.
The binary drivers are digitally signed by Red Hat, and will work on 32-bit and 64-bit versions of Windows
Installation
Using the ISO
You can download the latest stable or you can download the most recent build of the ISO.Normally the drivers are pretty stable, so one should try out the most recent release first.
You can access the ISO can in a VM by mounting the ISO with a virtual CD-ROM/DVD drive on that VM.
Wizard Installation
You can use an easy wizard to install all, or a selection, of VirtIO drivers.
- Open the Windows Explorer and navigate to the CD-ROM drive.
- Simply execute (double-click on) virtio-win-gt-x64
- Follow its instructions.
- (Optional) use the virtio-win-guest-tools wizard to install the QEMU Guest Agent and the SPICE agent for an improved remote-viewer experience.
- Reboot VM
