That's an interesting idea. We did do some very limited testing on qemu
with one iteration of our work. However, it's difficult because there is
no support for any RDMA devices which are a part of our primary use
case. I also imagine it would be quite difficult to develop those models
given the array of hardware that needs to be supported and the deep
functional knowledge required to figure out appropriate restrictions.
