Ask HN: ARM Macs – Will/How Docker, Vagrant, Virtual Box with x86 Linux Work?

Was looking into Vagrant/Docker, and VS Code remote containers last yesterday while trying to setup cleaner env for some stuff when I couldn't answer the question as to how all of this will work in the ARM MacOS world?

Even if Docker/Vagrant... are ported, what about Virtual Box and will we be limited to ARM Linux images? If yes, would that be the end of Macs as a dev machine. If we are able to run x86 images, what sort of a performance penalty, due to the difference in architecture?

In a way this may also have a bearing on my next Macbook Pro upgrade, and to ARM or not to ARM.

Are my concerns real or unjustified?
