Cloud Hypervisor is the open-source, Rust-based VMM started originally by Intel engineers but under the stewardship of the Linux Foundation has evolved into a nice multi-vendor initiative with the likes of Microsoft, Cyberus, Arm, and others all contributing. Even with Intel's cutbacks due to their ongoing corporate restructuring, the Cloud Hypervisor project is thriving as a multi-vendor open-source project for a security-focused hypervisor.

Cloud Hypervisor 47 was released on Tuesday and brings block device error reporting to guests, nicer error messages on exit, and a variety of bug fixes.

The nice error messages on exit for Cloud Hypervisor 47 are much improved over the basic error messages previously printed. Philipp Schuster of Cyberus Technology who worked on the new error messages [1]described the improvement as " a major step forward in UX for both users and developers. It will be clearer where an error originates from and still all debugging information will be preserved. "
