For what began as an Intel open-source project focused on delivering a modern VMM for cloud workloads and written in Rust is seeing increasingly more exposure on AArch64 and Microsoft Windows platforms. In fact, Intel remains largely inactive now with Cloud Hypervisor after their lead maintainer left the company last year and has now been one year since seeing any significant contributions from Intel to this open-source project.

Cloud Hypervisor brings more Microsoft Hyper-V (MSHV) support improvements. In particular, better MSHV support on 64-bit ARM (AArch64). MSHV with AArch64 now supports firmware boot as well as graceful guest shutdown and other improvements. Plus there is now continuous integration (CI) coverage for AArch64 with MSHV to help solidify the support.

Cloud Hypervisor 49 also brings logging improvements, VirtIO network changes, and a variety of bug fixes.

Engineers from Microsoft, Cyberus Technology, Rivos, Tencent, and Crusoe.ai worked on the Cloud Hypervisor 49 release. Intel didn't contribute to this release but Bo Chen who was the original maintainer for Cloud Hypervisor (and Kata Containers) at Intel before departing last year does remain active through his current employment at Crusoe.ai.
