Cloud Hypervisor is a high-performance, security-focused VMM that supports modern cloud workloads on common hardware architectures. It's implemented in Rust and based on the Rust VMM crates.
Cloud Hypervisor is a computer program that helps other programs run safely and efficiently on a computer. It's like a referee in a game, making sure everything runs smoothly and securely. It's written in a programming language called Rust, which is known for being safe and efficient.
Analysis
Cloud Hypervisor is an open-source Virtual Machine Monitor (VMM) that runs on top of the KVM hypervisor and the Microsoft Hypervisor (MSHV). It focuses on running modern, cloud workloads, on specific, common hardware architectures. The project's objectives include running on KVM or MSHV, minimal emulation, low latency, low memory footprint, low complexity, high performance, small attack surface, and 64-bit support only. Cloud Hypervisor supports hotplug of CPUs, passthrough devices (VFIO), virtio-{net,block,pmem,fs,vsock} and memory resizing. It also supports direct kernel boot and firmware boot. The project is under active development, with stability guarantees made for the API and point releases. Cloud Hypervisor is built on top of the Rust programming language and uses the Rust VMM crates. It aims to be a general-purpose VMM for cloud workloads, not limited to container/serverless or client workloads. The project follows the governance and community guidelines described in the Community repository.
Key points
- Cloud Hypervisor is an open-source VMM that runs on top of KVM or MSHV
- It focuses on running modern, cloud workloads on common hardware architectures
- It supports hotplug of CPUs, passthrough devices (VFIO), `virtio-{net,block,pmem,fs,vsock}` and memory resizing
- It supports direct kernel boot and firmware boot
- It's built on top of the Rust programming language and uses the Rust VMM crates
If Cloud Hypervisor gains traction, it could lead to the development of more secure and efficient virtualization solutions, which could in turn improve the overall performance and reliability of cloud computing.
One potential risk of Cloud Hypervisor is that it may not be widely adopted, which could limit its potential impact. Additionally, the project's reliance on Rust and the Rust VMM crates may create dependencies that could make it difficult to maintain and update the project.
