`cloud-hypervisor` also supports direct kernel boot into a `vmlinux` ELF kernel or `bzImage`. In order to support virtio-fs and virtio-iommu we have our own development branch. You are of course able to use your own kernel but these instructions will continue with the version that we develop and test against.

Cloud Hypervisor embraces the rust-vmm project goals, which is to be able to share and re-use
as many virtualization crates as possible. As such, the Cloud Hypervisor relationship with the rust-vmm
project is twofold:
1. It will use as much of the rust-vmm code as possible. Any new rust-vmm crate that's relevant to the project
goals will be integrated as soon as possible.
2. As it is likely that the rust-vmm project will lack some of the features that `cloud-hypervisor` needs (e.g. ACPI,
VFIO, vhost-user, etc), we will be using the `cloud-hypervisor` VMM to implement and test them, and contribute them

Both of these are VMMs written in Rust with a focus on safety and security, like Cloud Hypervisor.
However we want to emphasize that the Cloud Hypervisor project is neither a fork nor a reimplementation of any of those
