Ability to pause, save state and restore VM

[dobegor]

Motivation

With ability to pause the VM, save it's state (memory, execution context) and restore it later
it'd be possible to created sandboxed environments with ability to migrate them.

Thanks for the interesting proposal! I suggest you to fill the same issue on https://github.com/wasmerio/wasmer since it heavily relies on the WebAssembly runtime.

Looking forward to this.
It's great how flexible wasi can be in this regards. Shiftable workloads.

It's under development wasmerio/wasmer#489.

Any news about this functionality ?

[Hywan]

Not yet. It's not a feature that is part of wasmerio/wasmer for the moment :-).

Closing this issue in favor of wasmerio/wasmer#480 :-).
