Let's write an x86 hypervisor in Rust from scratch!
- 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 cargo-binutils to use rust-objcopy and rust-objdump tools:
$ cargo install cargo-binutilsYour also need to install musl-gcc to build guest user applications.
$ git submodule init && git submodule update $ cd guest/nimbos/kernel $ make user $ make GUEST=on
$ cd guest/bios $ make
$ cd hypervisor $ make run [LOG=warn|info|debug|trace] ...... Booting from ROM..
