Image Pre-cache Support
Nova supports caching images on demand at the compute node level for
performance reasons, but provides no ability to schedule that activity
before a rollout or maintenance window. This long-requested feature
becomes even more important when considering Edge Computing
environments, limited bandwidth, as well as high-scale rapid
application deployment.
