## Introduction<a name="section11660541593"></a>

Quick Emulator \(QEMU\) can simulate the scenario where a kernel runs on different boards, so that the kernel no longer depends on physical development boards.

## Constraints<a name="section119744591305"></a>

QEMU applies only to the OpenHarmony kernel.

## Usage<a name="section169045116126"></a>

For details about the ARM architecture, see  [Qemu ARM Virt HOWTO](https://gitee.com/openharmony/device_qemu/blob/master/arm_virt/README.md). The RISCV architecture tutorial will be updated later.
