Hi all,

I was wondering if the virtio-msg demos we have for FFA work on Xen? I have some vague memory that they do.

I hope you are looking for this ?

I wonder if I can use the same lower-level virtio-msg-bus or ffa calls to move messages between a DomU/Linux and a QEMU backend in Dom0?

My tests were done with a Rust based backend with xen-vhost-frontent (entity that understands virtio-msg in host userspace and talks to backend).

Can someone point me to the code? Or documentation?

Hope you were looking for this only ?
