Xen 4.12 Improves Open-Source Hypervisor Virtualization Security

April 02, 2019 / Sean Michael Kerner

The open-source Xen Project announced the 4.12 release of its namesake hypervisor virtualization technology on April 2, providing organizations and cloud operators with improved performance and security features. The new release integrates an improved virtual machine introspection capability that can be used to detect potential zero-day vulnerabilities. The Argo hypervisor-mediated data exchange is another new capability that provides inter-domain communications across a virtualized workload domain. Xen 4.12 also provides a slimmed-down architecture that presents a smaller attack surface, which also helps to improve security.
