Static Partitioning and VM-to-VM Communication Mechanisms
summary
Claims that embedded setups need static partitioning not cloud-style virtualization, and compares four concrete VM-to-VM channels: virtio with unprivileged backends (demoed as PV network in a dom0‑less boot and works, though some patches aren’t upstream), Argo copy-via-hypervisor (fast, memory-copy, security against sender tampering, needs event + argo drivers; Linux enablement was a ~10–20 line patch), plain shared-ring via pre-shared memory (statically defined, portable, can be fastest if well implemented), and a PL data‑mover prototype still in development. Performance varies 2x–10x by configuration.
