嵌入式实时虚拟机ZVM

   
★ZVM（Zephyr-based Virtual Machine）项目是在开源实时操作系统 Zephyr RTOS （由Linux基金会托管）上构建的一款虚拟机管理器（Hypervisor），ZVM一方面继承了Zephyr RTOS的开源生态和特性， 另一方面为业界提供了一个原创的面向嵌入式场景的开源虚拟化平台解决方案。
★ZVM由湖南大学教授、 嵌入式与网络计算湖南省重点实验室主任谢国琪老师主导开发，这是一款面向嵌入式场景的 开源、实时、安全、轻量及易用的虚拟机管理平台，致力于成为嵌入式领域的“Linux-KVM”，构建混合关键部署的开源生态。 项目仓库中包含Zephyr RTOS内核、工具及虚拟化支持所需的一些代码，共同构成了ZVM的代码仓。
★ZVM使用 zephyrproject-rtos 所遵守的 Apache 2.0 许可证 ，主要开发语言为C/C++语言。Apache 2.0许可证是一种自由软件许可证，允许用户自由使用、修改和分发软件， 不影响用户的商业使用，因此可以直接作为商业软件发布和销售。
