How do you install the VirtIO HDD drivers for KVM on Windows 7?

Question

I'm trying to install Windows 7 64-bit on KVM. I created a VirtIO HDD in virt-manager, and connected the driver ISO from here. The only drivers I see for storage are for Windows Server 2008, and 2008 R2. I tried the 2K8 folder. It found the driver, Red Hat VirtIO SCSI controller, packaged by Canonical, Ltd but could not find the disk.

No new devices could be found. Make sure the driver files are correct and located on the driver installation media.

How do I get the Windows 7 installer to find my drive?

Solution

You have to use the correct drivers for your OS or, as you've discovered, it won't work. The driver ISO that you're using is old. The current drivers are located at https://fedoraproject.org/wiki/Windows_Virtio_Drivers. They're signed by Red Hat so that they'll install on Windows without complaint.

You'll need the viostor driver.
