[Openstack-operators] A concept feature named 'scheduling live migration'

Yep, it seems that our purposes are maintenance/test both.
BTW, if one admin/oprator want to maintenance a host, he/she may want to relocate  all instance to another health node.
If there is a command just like  'nova live-migrate --all' and he/she need not care about selecting which node as destination, all works will be done by nova-scheduler.

Best wishes,
Yale Yuan

Hi Yuan ,
would it be similar somehow to the feature which allows you to disable a service via keystone on a server?

Hi all,
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.

Best wishes,
Yale Yuan
