<div>Hi,<br></div>
<div> </div>
<div>This setting, how does it display in the "nova show $UUID" or in the "openstack server show $UUID"? Ie, I don't want a VM showing ERROR state if the VM itself is not in error. A failed migration doesn't leave the VM down (well, not always) but error generally implies it is down. If this is more of an internal status, then +1. I'll look at the code shortly but wanted to get a reply off first. <br></div>

<div>To clarify, this is only about the state of a migration not an instance. If as an admin you list or show your migrations this would affect how that is displayed. Nothing about the instance, or how it's displayed, will change.<br></div>

<div>ALSO: It would have been very very helpful to see "live-migration" in the subject line.<br></div>

new periodic task '_cleanup_incomplete_migrations’ was introduced that runs on each compute node which queries for deleted instances and migration status in “error” status. If there are any such instances, then it simply cleanup instance files on that particular
compute node.</span></span></span><span class="colour" style="color:black"><span class="font" style="font-family:Tahoma, sans-serif"><span class="size" style="font-size:10pt"><u></u><u></u></span></span></span><br></p></div>

But in case of live migration,
the migration status is set to “failed” instead of “error” status if migration fails for any reason. This change was introduced in patch [3] when migration object support was added for live migration. Due to this inconsistency, the periodic task will not pickup
instances to cleanup orphaned instance files. To fix this problem, we simply want to set the migration status to “error” in patch [4] same as done for resize operation to bring consistency to the code.</span></span></span><span class="colour" style="color:black"><span class="font" style="font-family:Tahoma, sans-serif"><span class="size" style="font-size:10pt"><u></u><u></u></span></span></span><br></p></div>
