[PATCH v4 0/8] vhost: support for cross endian guests
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

[PATCH v5 0/8] vhost: support for cross endian guests
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
