Creating Windows virtual machines using virtIO drivers
Fedora infrastructure hosts virtIO drivers and additional software agents for Windows virtual machines running on kernel-based virtual machines (KVM). virtIO is a virtualization standard for network and disk device drivers.
Fedora cannot ship Windows virtIO drivers because they cannot be built automatically as part of Fedora’s build system: the only way to build Windows virtIO drivers is on a machine running Windows. In addition, shipping pre-compiled sources is generally against Fedora policies. Microsoft does not provide virtIO drivers, you must download them yourself in order to make virtIO drivers available for Windows VMs running on Fedora hosts.
For details on downloading the drivers, please see: https://github.com/virtio-win/virtio-win-pkg-scripts/blob/master/README.md
