Cloud Hypervisor and Kata Containers: A path towards modern virtualization
summary
Kata Containers is integrated with Cloud Hypervisor to run each container inside its own VM using the rust‑vmm stack and aims for minimal emulation, low latency and small memory footprint. The integration uses Cloud Hypervisor (rust-vmm) with virtiofsd, vsock, VFIO, virtio‑blk and ACPI hotplug to provide file sharing, runtime‑to‑agent comms, device passthrough and live CPU/memory changes. End‑to‑end tests run in CI and support docker, containerd, CRI‑O, Podman and Kubernetes, and the implementation is reported as fully working for those use cases.
