Real-Time Systems’ RTS Hypervisor 2.2 bare metal hypervisor features shared cache and interrupts. It permits the use of message signaled interrupts (MSIs) even if the client operating system does not. MSIs allow the sharing of interrupts, preventing conflicts or forced partitioning of the underlying system. The latest version’s open control module provides a high-performance virtual network interface, shared memory, and other virtualization components for paravirtualize clients.
