很实用。个人感觉比七牛方便。可以在vDSM内反代---理论上会影响些性能（但个人用无所谓）。
不影响小鸡本身运行其他服务。仅个人看法，勿喷。可能是因为我比较熟悉群晖的软件，也方便跟家里云配合用。
下面这个‘nested virtualization’我没懂，厂商不允许吗？
还有个玩法，你的群晖授权可以用在vDSM上，因为是官方允许的方式--当然只能用在一台上。图3的三个备份软件就非常优秀。

就是VM-x/AMD-V : ✔ Enabled需要是开启的。

After that you can run the following commands in Linux to check your system:

sudo apt install cpu-checker
sudo kvm-ok
If you receive an error from kvm-ok indicating that KVM cannot be used, please check whether:

the virtualization extensions (Intel VT-x or AMD SVM) are enabled in your BIOS.

you enabled "nested virtualization" if you are running the container inside a virtual machine.

you are not using a cloud provider, as most of them do not allow nested virtualization for their VPS's.
