008 Inter-VM Communication Mechanisms

Status

Proposed

Context

Guest VM software needs to communicate with software in other guest VMs.

Decision

Spectrum provides two mechanisms for inter-guest communication:

  • TCP/IP with virtio-net

  • Cross-domain virtio-gpu which can send references to shared memory and be used as a transport for a stream protocol, e.g. Wayland.

Consequences

  • Examples will be required on how to write applications which communicate over virtio-gpu.
