[PATCH] Change virtio_pci to use a shared memory area for config
This patch changes virtio_pci to use a shared memory area for virtio config
info instead of using the PCI configuration space. This is closer semantically
to what the virtio API exposes and is it a lot easier to implement on both
ends.

[patch 00/43] lguest: Patches for 2.6.24 (and patchbomb test)
Hi all,
These are the patches I'm planning to submit for 2.6.24. Comments
gratefully accepted. Along with the usual cleanups and improvements are Jes'
de-i386-ification patches, and a new "virtio" mechanism designed to be shared
with KVM (and hopefully other hypervisors).
Cheers,
Rusty.
