RVM-Tutorial
Let's write an x86 hypervisor in Rust from scratch!
Features
- Lightweight enough, only 3K+ LoC
- Supported guest OS: NimbOS
- Guest/host memory isolation with nested paging
- Device emulation:
- serial port I/O
- APIC timer
- Currently, only supports single core single vCPU and single guest
Install Build Dependencies
Install cargo-binutils to use rust-objcopy and rust-objdump tools:
$ cargo install cargo-binutils
Your also need to install musl-gcc to build guest user applications.
Build Guest OS
$ git submodule init && git submodule update
$ cd guest/nimbos/kernel
$ make user
$ make GUEST=on
Build Guest BIOS
$ cd guest/bios
$ make
Build & Run Hypervisor
$ cd hypervisor
$ make run [LOG=warn|info|debug|trace]
