The device endianness doesn't change during runtime.
What are you talking about? Of course it does.
The host CPU certainly does, but the virtio device doesn't... Does it?
This check only consider the device, not the CPU:
bool virtio_access_is_big_endian(VirtIODevice *vdev)
{
#if defined(LEGACY_VIRTIO_IS_BIENDIAN)
return virtio_is_big_endian(vdev);
This is set for both ARM and PPC, which checks current cpu endianness in both
cases.
and once the features are negotiated it doesn't seem to change.
Incorrect.
