Hi all, A host / guest communication channel can be useful in a lot of scenarios. What about thinking on a common interface to be implemented on other hypervisors as well and not only on KVM? We're planning to start working on something similar for Hyper-V and there were some chats about ideas related to XenServer as well (John?).
Each hypervisor provides different ways of achieving this goal, but IMO it'd be fairly easy to define a common adapter interface. Alessandro On Sep 30, 2013, at 20:21 , Daniel P.

Today Nova enables to launch guests of different types. For real deployments we would need appliances from various vendors to run as instances. Appliances can be Loadbalancer, Firewall, IPsec, Routers or UTM etc., These appliances can be tied up with Neutron Services and would need configuration from various services like FWaaS, LBaaS, VPNaaS etc., One way to configure these appliances from Neutron Agents is by opening up the so needed virtio unix channel socket and reach the configuration daemon in the appliance. Other approach is by having a separate network for management activities and having agent to communicate to a daemon in netns to reach out to appliance. Thanks, this is the kind of usage information I was asking for, wrt host integration. This shows the use case for virtio-serial is as a mechanism for integration between infrastructure pieces controlled by the cloud admin, not as something that is targetted towards end users of the cloud. I think we need to have a detailed blueprint for this, describing the use case(s) to be addressed and proposing some possible design(s).
