It is a lighweight VM and uses the same technology as Firecracker

It is planned but not yet implemented. But it is absolutely possible.

I would consider Docker for VMs instead. In a similar way, it focuses on dev ops type use case like deplying apps, etc.
> How do I get data in/out?
There is an SDK and server that help does that and file streaming is planned. But right now, you can execute commands in the VM and get the result back via the server
> AWS built [Firecracker (which is built on KVM)] to power Lambda and Fargate [2], where they need to quickly spin up isolated environments for running customer code. Companies like E2B use Firecracker to run AI generated code securily in the cloud, while Fly.io uses it to run lightweight container-like VMs at the edge [4, 5].
How is it so fast? Is it making any trade offs vs a traditional VM? Is there potential the VM isolation is compromised?
Can I run a GUI inside of it?
Do you think of this as a new Vagrant?
How do I get data in/out?
