Xen 4.12 Improves Open-Source Hypervisor Virtualization Security

The new release integrates an improved virtual machine introspection capability which 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.
