- I need to install a Windows virtual machine (VM) using virtio but Windows cannot find the device. How do I install the drivers needed?
virtio-winpackage on the RHEV-M system which is found in the
rhel-x86_64-server-supplementary-6channel. If the system is not subscribed to that channel, log on to RHN and subscribe the system to that channel, then run the following command:
yum install virtio-win
Locate the virtio-win packages and upload the *.vfd and *.iso files to the ISO storage domain using the ISO uploader utility:
rhevm-iso-uploader --iso-domain=nameOFdomain upload /usr/share/virtio-win/*.vfd rhevm-iso-uploader --iso-domain=nameOFdomain upload /usr/share/virtio-win/*.iso
- Create a new VM with a VirtIO disk interface (instead of IDE).
When the Windows VM is created, attach
virtio-win-xxxx.vfdas a floppy, using the Run once menu (Remember to also boot from the Windows Installation ISO using "Attach CD").
VirtIO Win amd64 VFD - for 64 bit architecture VirtIO Win x86 VFD - for 32 bit architecture
For deploying a large number of VirtIO-based VMs, a better solution would be to slipstream the
VirtIO_blkdriver into the Windows distribution ISO file. This is possible using nLite software or the tools Microsoft provides for driver slipstreaming.

Proceed according to the version of Windows used:
- When Windows prompts for the driver, click on "Load Driver", point the installer to drive A: and pick the driver that suits the OS (32-bit use x86 drivers, 64-bit use AMD64 drivers)
Windows 2008 R2:
- Choose the AMD64 drivers.
- There is a known issue where the automatic driver scanning in Windows fails to detect the correct driver. The workaround is to select the driver manually similar to the process listed below for Windows 7.
- Choose the AMD64 drivers.
- When Windows prompts for the driver, click on "Load Driver", point the installer to drive A: and pick the SCSI controller driver for Windows 7.
- When Windows prompts for the driver, click on "Load Driver", point the installer to drive A: and pick the SCSI controller driver for Windows 8.
- The latest versions of RHEL have built-in support for VirtIO.
