Hi, This patchset allows vhost to be used with legacy virtio when guest and host have a different endianness. Patch 7 got rewritten according to Cornelia's and Michael's comments. I have also introduced patch 8 that brings BE vnet headers support to tun/macvtap. This series is enough to have vhost_net working flawlessly. I could succesfully reboot guests from ppc64 to ppc64le and

Only cosmetic and documentation changes since v5. --- Greg Kurz (8): virtio: introduce virtio_is_little_endian() helper tun: add tun_is_little_endian() helper macvtap: introduce macvtap_is_little_endian() helper vringh: introduce vringh_is_little_endian() helper vhost: introduce vhost_is_little_endian() helper virtio: add explicit big-endian support to memory

Hi, This patchset allows vhost to be used with legacy virtio when guest and host have a different endianness. It is compatible with modern virtio and can be fully compiled out through kernel config. FWIW, I could flawlessly kexec/reboot guests from ppc64 to ppc64le and back. I could also migrate from a ppc64 to a ppc64le host and back. No regressions on x86 as expected. My experimental QEMU tree
