There is a feature in my mind just as below:
In VMware, admin can use maintenance mode to set a host to entering maintenance mode, in which the host does not allow you to deploy or power on a virtual machine until all running virtual machines are powered down or migrated to different hosts.
So, if there is a feature that enable scheduler while live migration rather than use destination hostname argument in shell command 'nova live-migration <instance-uuid> <hostname>', OpenStack can implement maintenance mode too. In other words, operator can migrate instance without specific destination hostname.
If anyone has some suggestions, please feel free to let me know.
