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
