<br>
<br>
I think I have found an inconsistency between nova cli and Horizon
in the way they send live migration commands to nova API. I'm not
sure where this needs to be fixed, so please advise on that.
<br>
<br>
The situation:
<br>
<br>
I try to live-migrate a VM, and I do it through nova cli and
through Horizon, and nova-api logs contain different data
depending on the way I do it.
<br>
<br>
1. nova cli
<br>
<br>
I run the command:
<br>
<br>
nova live-migration 17359460-d23c-4acc-a9b1-5cf117b54430
<br>
<br>
and it shows up in nova-api logs as:
<br>
<br>
{"os-migrateLive": {"block_migration": "auto", "host": null}}
<br>
<br>
2. horizon
<br>
<br>
I run live migration via Horizon with unchecked Disk Overcommit
and unchecked Block Migration.
<br>
<br>
It shows up in nova-api logs as:
<br>
<br>
{"os-migrateLive": {"disk_over_commit": false, "block_migration":
false, "host": null}}
<br>
<br>
This difference can lead to different parameters provided for live
migration when block_migration: auto is translated into
block_migration: true.
<br>
<br>
My environment:
<br>
<br>
Openstack Stein
<br>
<br>
CentOS Linux release 7.6.1810
<br>
