Any comments are welcome! thanks!
What features/modules were you thinking of? Were you thinking of turning them into dynamically loaded libraries, or spinning them out into separate projects (such as libslirp)? Also, what is the use case? Is it to reduce the attack surface without having multiple QEMU binaries? Having dynamically linked libraries would go even beyond what rust-vmm does; Rust binaries in the end statically link every crate that they use, rust-vmm's purpose is mostly to share code across VMMs and avoid forks. It may also have a startup time penalty which has to be considered. Thanks, Paolo
