Another iteration of virtio-1 patches for qemu, as always available on git://github.com/cohuck/qemu virtio-1 This one seems to work together with the current vhost-next patches (well, I can ping :) Changes from v4: - add helpers for feature bit manipulation and checking - use 64 bit feature bits instead of 32 bit arrays - infrastructure to allow devices to offer different sets of feature bits

And yet another iteration of virtio-1 support in qemu, tested with the latest virtio kernel patches. Find it at git://github.com/cohuck/qemu virtio-1 Changes from v5: - fixed stupid bug in "virtio: support more feature bits": we need to define a proper prop backend for 64 bit wide handling... - don't negotiate revision 1 unless VERSION_1 is offered - use 64 bit wide features

Hi, This series allows QEMU to use vhost with legacy virtio devices when host and target don't have the same endianness. Only network devices are covered for the moment. I had already posted a series some monthes ago but it never got reviewed. Moreover, the underlying kernel support was entirely re-written and is still waiting to be applied by Michael. I hence post as RFC. The corresponding
