| 09:34:12 | bauzas | the point is, I feel we are more and more designing our 'high-performance' features based on a couple of assumptions which are virt-specific | |

| 09:34:59 | bauzas | which makes sense as we honestly only have one major configuration using a couple of knobs we know (ovs, libvirt-qemu for the least) | |

| 09:36:18 | bauzas | if some company wants to develop a new neutron backend that would break the 1:1 mapping between the agent and the service itself, then this would require more work for them | |

| 09:36:51 | bauzas | for the moment, I'd say (except notably for QoS) that only the libvirt driver is impacted by such assumption | |

| 09:37:34 | bauzas | when sean-k-mooney say "a lot of changes for nova and neutron" , this would mean for nova the libvirt driver only, as I could tell | |

| 09:44:14 | bauzas | sean-k-mooney: huh to what you say, you'd say that we could want to have multiple SLAs on different datapaths ? | |
