During nova-compute downtime guest instances cannot be controlled; also instances may become unresponsive because of host/guest failures. This session is to explore what extensions could be added to nova-compute drivers (and related API) so that guest instance management is enriched with HA capabilities. Things like: - restarting HA-enabled VMs impacted by host failures. - reallocating VMs on a host coming back to life. and live migration based on predictive mode failures could be compelling features for certain types of workloads.
