[Bug 1799340] [NEW] The default_ephemeral_device in instances table is NULL when deploying a VM
Public bug reported:
Description
===========
I deploy a vm with flavor:
+----------+-----------+------+-----------+------+-------+-------------+---------
| Name | Memory_MB | Disk | Ephemeral | Swap | VCPUs | RXTX_Factor |
+----------+-----------+------+-----------+------+-------+-------------+-----------+-------------+
| smy_test | 512 | 10 | 5 | 1 | 2 | 1.0 | True | - |
+----------+-----------+------+-----------+------+-------+-------------+---------
When the VM is deployed successfully and running normally,the default_ephemeral_device is not updated in instances table in database. Obviously default_swap_device and root_device_name is updated.
+------------------+--------------------------+---------------------+
| root_device_name | default_ephemeral_device | default_swap_device |
+------------------+--------------------------+---------------------+
| /dev/vda | NULL | /dev/vdc |
+------------------+--------------------------+---------------------+
Steps to reproduce
==================
1. create a flavor using ephemeral
2. deploy a VM with this flavor
Expected result
===============
check instances table and default_ephemeral_device is NULL;
Actual result
=============
default_ephemeral_device has a value;
Environment
===========
