This patchset aims to get us some way to implement virtio-1 compliant and transitional devices in qemu. Branch available at git://github.com/cohuck/qemu virtio-1 I've mainly focused on: - endianness handling - extended feature bits - virtio-ccw new/changed commands Thanks go to Thomas for some preliminary work in this area. I've been able to start guests both with and without the virtio-1 patches in the linux guest patchset, with virtio-net and virtio-blk devices (with and without dataplane). virtio-ccw only :) vhost, migration and loads of other things have been ignored for now. I'd like to know whether I walk into the right direction, so let's consider this as a starting point.
