Hi all,<br>
<br>
I found and reported a unkind behavior of "openstack server migrate" command<br>
when I maintained my environment.[1]<br>
But, I'm wondering which solution is better.<br>
Do you have opinions about following my solutions by operating point of<br>
view?<br>
I will commit a patch according to your opinions if those are gotten.<br>

[Actual]<br>
If user run "openstack server migrate --block-migration <UUID>",<br>
openstack client call Cold migration API.<br>
"--block migration" option will be ignored if user don't specify "--live".<br>
<br>
But, IMO, this is unkindly.<br>
This cause unexpected operation for operator.<br>

+1 This has confused/annoyed me before.<br>

<br>
P.S.<br>
"--shared-migration" option has same issue.<br>
</blockquote>
<br>
For the shared migration case, there is also this bug:<br>

<br>
which, if fixed/implemented would negate the need for<br>
--shared-migration? And would fix also "nova resize" on shared<br>
storage.<br>

In my understanding, that report says about libvirt driver's behavior.<br>
In the other hand, my report says about the logic of openstack client.<br>
<br>
Current "openstack server migrate" command has following logic:<br>
<br>
* openstack server migrate<br>
+-User don't specify "--live"<br>
| + Call cold-migrate API.<br>
| Ignore "--block-migration" and "--shard-migration" option if user specify those.<br>
|<br>
+-User specify "--live"<br>
| + Call live-migration API.<br>
|<br>
+-User specify "--live --block-migration"<br>
| + Call block-live-migration API.<br>
|<br>
+-User specify "--live --shared-migration"<br>
+ Call live-migration API.[1]<br>
<br>
[1]<br>
"--shared-migration" means live-migration(not block-live-migrate) in "server migrate" command.<br>
In other words, "server migrate --live" and "server migrate --live --shared-migration"<br>
are same operation.<br>
I'm wondering why "--shared-migration" is existed...<br>
<br>
