KVM developers released the first update of the windows paravirtual network drivers a few days ago so I think a post is warranted in documenting the upgrade procedure.

Today KVM maintainers, qumranet, published the second release of the windows paravirtual network drivers adding support for 64-bit as well as SMP guests.

In this article I will outline how to configure bridged networking to a tap interface on a Fedora KVM host as there seems to be a lack of good documentation on how to do this.

Linux Kernels from 2.6.25 and later come with built in paravirtual network and block device drivers so that they can run as paravirtual guests on KVM host running on release 60 or later.

KVM-64 was released today featuring pci hotplug, paravirtual mmu and improvied PIT accuracy.
