1.1. 带外管理
带外管理也不是个问题，如果:
- 服务器自带BMC。
- 你有能力让服务器厂商给你定制，因为你需要定制BIOS部分功能以让其在启动时认到智能网卡提供的虚拟设备。
但是，由于多数用户没有让服务器厂商高度定制服务器的能力，因而我们需要在“无米”的状态下做“炊”。

Porting KVM to NVIDIA Jetson Nano
因为Jetson如果作为边缘设备，那么我们需要进一步探索虚拟化在其上的可能性，从而使FT有更容易的路线可走，还有既然它的芯片是PCIE的，那理应可以透传。

什么build rootfs、uboot之类的就不要了，那是后期嵌入式的活，我们在现有环境上build kernel即可。
