My concern is to someone unfamiliar with OpenStack terminology, the word \"instance\" doesn\u0027t convey \"VMs, bare metal and containers\". So the dilemma is how to ensure the reader understands the full meaning without getting unnecessarily wordy. I am not thrilled with this solution but one answer is to elaborate \"instance(e.g. VMs, bare metal or containers)\" It\u0027s not elegant, but it does make the broad application of storage services Cinder is offering.\n\nAlso as I am just coming up to speed using Gerrit I missed your comments from a couple of weeks back - I\u0027ll pay more attention going forward.","commit_id":"db306a1e312788a8bedf2ed9e76a84388ccdc92d"},{"author":{"_account_id":10439,"name":"Xi Yang","email":"yang.xi@99cloud.net","username":"phenom"},"change_message_id":"767be9a7b99dd53839f644e7446cc9ea12b35863","unresolved":false,"context_lines":[{"line_number":7,"context_line":"(LUNs or Volumes) on which a virtual machine can be provisioned"},{"line_number":8,"context_line":"or which can be added to support applications running on an"},{"line_number":9,"context_line":"existing virtual machine.
