The Hypervisor Hierarchy: Why Architecture Matters for Performance, Security, and Flexibility
summary
Xen claims a true Type 1 architecture that runs directly on hardware and supports both dom0 for dynamic VM creation and dom0less predictable low-latency setups for automotive/industrial use. It asserts a much smaller trusted computing base than KVM (no full host OS), which shortens safety certification paths; it runs on x86, ARM and RISC‑V and traces back to EC2’s original hypervisor. The project provides XCP‑NG as a turnkey distro and an open GitLab CI on real hardware that runs tests over serial ports so vendors can validate commits on custom boards.
