[PATCH RFC 0/7] vhost: cross-endian support (vhost-net only)
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.

[PATCH RFC v6 00/20] qemu: towards virtio-1 host support
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
