This package wraps the lower-level crate [linux_io] to provide more
convenient access to the linux KVM API, which allows you to create and
run kernel-managed virtual machines on architectures that support that.
For now this crate is largely just serving as a prototype case for building
low-cost safe abstractions on top of [linux_io], so it doesn't support
the full KVM API. Hopefully over time it'll gain enough to be useful.
