VMtoVM
VMtoVM is a concept and set of software components that enable direct communication between virtual machines (VMs) across hosts and hypervisors. The goal is to provide low-latency messaging, efficient coordination, and secure data exchange without requiring traffic to traverse external networks or proxy layers. VMtoVM typically layers a transport protocol, a VM addressing and identity scheme, and a set of APIs for messaging, remote procedure calls, or shared-state operations.
Architecturally, VMtoVM comprises a VM-embedded agent or shim, a cross-host transport channel, and a coordination plane
Interoperability is not standardized, and multiple projects propose compatible wire formats and API contracts to enable
Common use cases include service-to-service communication between VMs, cross-hypervisor task coordination, and lightweight tracing or debugging
External references and related topics include inter-VM communication, virtualization, hypervisors, and virtual networking.
