All, Some time ago during discussion we noticed that we are missing ability to send/receive events from vdsm client [1]. Initially we thought that having [2] would be enough to support notification between engine and vdsm. Now we know we need it for [1]. I would like to collect potential use cases from mom, hosted engine and others so we could design the api to enable them. As part of the work I would like to see whether there is a need to have global event topic or have name convention and use more granular queues. Do we have any use cases to subscribe to additional topic(s) during life time of a client or subscription during instantiation is good enough. Thanks, Piotr [1] https://github.com/oVirt/vdsm/blob/master/lib/vdsmclient/client.py [2] https://github.com/oVirt/vdsm/blob/master/vdsm/clientIF.py#L149
