AFAIU because of this something like -global memory-backend-file.share=on (as proposed by https://lists.nongnu.org/archive/html/qemu-devel/2019-12/msg00531.html) can not be used to make the main RAM shared (e.g. for vhost on s390x). Or am I wrong? If not, is -global still the way we want to make this work for non-numa machines, or did I miss updates? Regards, Halil
