Per the discussion at the Train Forum [1] this deprecates the problematic --live option on the server migrate command which, depending on the compute API version used, forcefully bypasses the scheduler and also does not allow you to live migrate a server and let the scheduler pick a host. The --live option is replaced here with two new options: * --live-migration: this simply tells the command you want to perform a live rather than cold migration; if specified with --live the --live-migration option takes priority. * --host: when specified, this will request a target host for the live migration and will be validated by the scheduler; if not specified, the scheduler will pick a host. This option is mutually exclusive with --live. We can build on the --host option by supporting cold migrations with a specified host when using compute API version 2.56 or greater but that will come in a separate change. If the --live option is ever used we log a warning. Note there are several related changes for this issue: - https://review.openstack.org/#/c/628334/ - https://review.openstack.org/#/c/626949/ - https://review.openstack.org/#/c/627801/ - https://review.openstack.org/#/c/589012/ - https://review.openstack.org/#/c/460059/ This change allows us to deprecate the --live option and provide a replacement which is backward compatible without having to use something potentially error-prone like nargs='?'.
