Secure isolation in Rust
summary
A lightweight hypervisor library called LibKVM rust library is implemented in Rust atop the Linux KVM kernel module, using ioctl calls, #[repr(C)] structs, and extern/no_mangle builds to produce .so libraries callable from C or scripting languages. The claim is VMs can be as fast as containers (KVM, Firecracker, light VM results), while Rust eliminates spatial and temporal bugs through memory safety via ownership/borrowing but does not mitigate hardware flaws like Spectre/Meltdown.
