New project

8 of 11

New ServiceVM/DeviceManager project

  • Moving out of Neutron for an independent project
  • drivers for advanced services will remain in Neutron
  • common library would go for oslo eventually

Project goal/scope

  • provide unified interface to not only Neutron, but also other openstack project
  • service/device life cycle management
    • accounting
  • communication channel to guest agent that runs in ServiceVM: oslo.messaging
  • driver interface for them
    • create/delete ServiceVM/device
    • transport to config device
    • transport to conifg management
