[Bug 1803941] [NEW] UnicodeDecodeError occurs when non-ascii char in the instance name/description

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

Description
===========
When using the non-ascii character in the instance description, the new instance spinning up fails due to the UnicodDecodeError in the nova-scheduler.
We are using the pike version nova in ubuntu. (16.1.4). The python env is py27

Steps to reproduce
==================
1) Add some no-ascii char into the instance description.
nova update --description "testing 测试" 2eda7ea7-94f1-4ad9-8ea5-f4f007bb4e4d

2) restart the nova-scheduler process
3) spin up a new instance. Then The new instance scheduling is failed.

The fix is remove non-ascii character and restart the nova-scheduler.

  ===========
  When using the non-ascii character in the instance description, the new instance spinning up fails due to the UnicodDecodeError in the nova-scheduler.
  We are using the pike version nova in ubuntu. (16.1.4). The python env is py27

  1) Add some no-ascii char into the instance description.
  nova update --description "testing 测试" 2eda7ea7-94f1-4ad9-8ea5-f4f007bb4e4d

  2) restart the nova-scheduler process
  3) spin up a new instance. Then The new instance scheduling is failed.

  The fix is remove non-ascii character and restart the nova-scheduler.
