Re: About Inter-VM Communication - Shared Memory
Wo, you mean ivshmem shared memory privilege for each VM, actually you already referred the doc : ) https://projectacrn.github.io/latest/developer-guides/hld/ivshmem-hld.html
Specific to ivshmem, actually it is a simple protocol for virtual VM communication from qemu, just mapping share memory as virtual PCI device in VM. There is no privilege control for each VM, so in ACRN inter-vm commutation, we also follow the same way, no difference for each VM of shared memory R/W.
But if you have hard request for Write control, you can implement it in upper layer application or software right.

thank you for your reply, yes I would like to arrange that one vm can read/write to the shared memory (ivshmem) and one of them can only read from there.
