base on A mini x86 hypervisor # MVisor: A mini x86 hypervisor ## Goal 1. A minimal hypervisor based on KVM and x86 (replace QEMU) 2. A limited number of emulated devices (support plugins in later version) 3. Linux and Windows as guest VMs 4. VFIO (especially vGPU) and migration 5. Extremely stable and high performance ## Screenshot ### Ubuntu <img src="./docs/ubuntu.jpg" width="640"> ### vGPU <img src="./docs/vgpu.jpg" width="640"> ### Multimedia <img src="./docs/multimedia.jpg" width="640"> ## Roadmap And Current Status What's supported now: ### Basic functions 1. 440FX ✅ / Q35 Chipset ✅ 2.

Live migration ✅ ## Compile & Run ### For RockyLinux 9.3, ```bash dnf install epel-release gdb cmake gcc-c++ acpica-tools dnf --enablerepo=devel install -y protobuf-compiler protobuf-devel glib2-devel yaml-cpp-devel pixman-devel libzstd-devel zlib-devel # If SDL enabled dnf --enablerepo=devel install -y SDL2-devel alsa-lib-devel ``` ### For Debian 12, ```bash apt install meson gdb cmake build-essential g++ acpica-tools apt install protobuf-compiler libprotobuf-dev libglib2.0-dev libyaml-cpp-dev libpixman-1-dev libzstd-dev zlib1g-dev # If SDL enabled apt install libsdl2-dev libasound2-dev ``` ### Compile and Run ```bash meson setup build -Dsdl=true # SDL is disabled by default meson compile -C build ./build/mvisor -c config/sample.yaml -vnc 5900 ``` ## Paravirtualized Drivers An ISO image file is needed to install OS. Edit YAML file to configure image path.
