About Windows PV Drivers
Paravirtualization aware (PV) device drivers are an important part of HVM guests running under the Xen Project Hypervisor.
Citrix has provided a set of PV driver for Windows since the inception of XenServer. These drivers have evolved over the years and the full source code has been made available under a BSD license and are available to the community to modify and build upon.
The Windows PV Drivers team at the Xen Project is maintaining and developing these drivers under Xen Project governance.

The team plans to perform regular builds of the drivers and aims to test them using the Microsoft HCK. The team further plans to provide logo-signed builds of the drivers in future commercial Xen offerings. The team may also provide logo-signed drivers via Microsoft’s Windows Update mechanism, making them widely available to anyone running Windows under Xen (not just XenServer) without the need to build the drivers themselves. Any other organization is also free to do the same by registering a top-level PV device with the Xen Project community (see Xen PCI device ID registry) and logo-signing their driver builds.
Development builds can be found here.
