x86_64

Build and verify from public source

  1. Get the source

    git clone https://github.com/Aitaide/OpenXTOS.git
cd OpenXTOS

  2. Install dependencies

    sudo apt-get update
sudo apt-get install -y build-essential bc bison flex libssl-dev \
  libelf-dev cpio gzip rsync python3 kmod file qemu-system-x86

  3. Build

    JOBS=$(nproc) ./scripts/build_system.sh

  4. Run verification

    QEMU_TIMEOUT=180 ./scripts/verify_system.sh

RISC-V64 guest checks require OpenSBI. Run the matching verify_guest script for ARM64 and RISC-V64. QEMU checks validate software behavior, not real-hardware performance.
