Hello Isaku, Thanks for sharing this! Right now in Sahara project we think to use Marconi as a mean to communicate with VM. Seems like you are familiar with the discussions happened so far. If not, please see links at the bottom of UnifiedGuestAgent [1] wiki page. In short we see Marconi's

I agree those arguments. But I don't see how network-based agent approach works with Neutron network for now. Can you please elaborate on it? Here is the scheme of network-based agent: server - MQ (Marconi) - agent As Doug said, Marconi exposes REST API, just like any other OpenStack

Also, how are you proposing to deal with live migration of VMs ? The virtio serial channel can get closed due to QEMU migrating while the proxy is in the middle of sending data to the guest VM, potentially causing a lost or mangled message in the guest and the sender won't know this if this
