Some notes before you use virtualbox with amd-v(amd-virtualization-technology)

1. Virtualbox can't get used along with `multipass` unless you set multipass backend to virtualbox

2. If you want to open another virtualbox system inside of a virtualbox container, you have to enable `VT-x/AMD-V` inside of `processor setting` tab.

> To do this, open the VirtualBox application and go to the “Settings” menu. In the “System” tab, you will find the “Processor” section. Here, you will need to uncheck the “Enable VT-x/AMD-V” option. This will disable hardware virtualization in VirtualBox.

3. If the two is not work for you, I mean `virtualbox` and `multipass`, you could try to use a docker container that was made by me: https://hub.docker.com/r/yingshaoxo/ubuntu_ssh_server_for_the_stupid_apple_macos_m1_system
