cluster-api-provider-virtink VS cloud-hypervisor

is an especially good fit for running fully isolated Kubernetes clusters in an existing Kubernetes cluster. See our Cluster API provider and the knest tool for more details.

There is no mention of cloud-hypervisor[1] (also in the rust-vmm ecosystem) in the article. It has the memory reclamation feature they require. It also support VFIO and virtiofs.

https://github.com/tandasat/Hypervisor-101-in-Rust is there to help

https://github.com/cloud-hypervisor/cloud-hypervisor isn't educational necessarily but is one of the most technically progressive fastest developing highest funded vm projects ever, and there are oodles of tech talks on it. I am not qualified to make any specific recommendations, but there's tons of stuff here.

> The goal of the Cloud Hypervisor project differs from the aforementioned projects in that it aims to be a general purpose VMM for Cloud Workloads and not limited to container/serverless or client workloads.

Firecracker is such a great piece of technology. I'm amazed that AWS actually open-sourced it. All kudos to them. We're using Firecracker at our company to allow API companies build interactive demos like this one we built for Prisma [1].

Relatively new project 'Cloud Hypervisor' https://github.com/cloud-hypervisor/cloud-hypervisor seems to launch images faster.

The Chrome OS hypervisor was then evolved/forked into Firecracker and Intel's Cloud Hypervisor, with the latter supporting both Linux and Windows. Perhaps Cloud Hypervisor would serve as a good backbone for sandboxing, with its Rust implementation and focus on security?

GitHub - cloud-hypervisor/cloud-hypervisor: A Virtual Machine Monitor for modern Cloud workloads. Features include CPU, memory and device hotplug, support for running Windows and Linux guests, device offload with vhost-user and a minimal compact footprint. Written in Rust with a strong focus on security.

Did you guys think about live migrations? https://github.com/cloud-hypervisor/cloud-hypervisor seems to support it and it shares a good amount of code with firecracker.

Virtink is a Kubernetes add-on for running Cloud Hypervisor virtual machines. By using Cloud Hypervisor as the underlying hypervisor, Virtink enables a lightweight and secure way to run fully virtualized workloads in a canonical Kubernetes cluster.
