[PATCH] virtio-pci: fix host notifiers on bi-endian architectures
...reduced upload performances... until you reboot,
migrate, managed save or in fact any operation that causes vhost_net
to be re-started. Network connectivity is then permanantly lost for
the guest.
TX falling back to QEMU is the result of a failed MMIO store emulation
in KVM. Debugging shows that:
kvmppc_emulate_mmio()
|
+-> kvmppc_handle_store()
|
+-> kvm_io_bus_write()
|
+-> __kvm_io_bus_write() returns -EOPNOTSUPP
This happens because no matching device was found:
__kvm_io_bus_write()

+->kvm_iodevice_write()

+->ioeventfd_write()
