Intel-Led Cloud Hypervisor 30 Released With CLI Changes To Reduce The Binary Size

Cloud Hypervisor as a reminder is what started out as an open-source Intel project to develop a modern hypervisor focused on cloud workloads and with security being among the leading concerns. Cloud Hypervisor more recently is developed as a Linux Foundation project but with Intel's software engineers being among the leading contributors to the project along with the likes of Arm, Tencent, Bytedance, and Microsoft.

Debuting this week was Cloud Hypervisor 30.0 as the newest feature update to this Rust-written VMM. Cloud Hypervisor 30.0 changes around one of its Rust crates for its command-line argument handling to reduce its binary size from about 3.6MB to 3.3MB. But with this changing around of the Rust crate from clap to argh, it does lead to several command line syntax changes. Moving forward now rather than --option=value the --option value syntax is required along with other CLI syntax changes for that slight savings to the binary size.

Cloud Hypervisor 30 also ships basic vfio-user server support, initial heap profiling support, and updated documentation. There are also a number of bug fixes with the new Cloud Hypervisor.
