The crate is in very early stage which only implements the skeleton and basic commands, so a long todo list:

I had a quick look. Nice work Liu, it looks like a very good start! I
hope I can start using & contributing to it soon.
Is there any user of the crate? In particular, do you have code to
manipulate the virtio rings?
