** Summary changed:
- ConfigDrive datasource fails when metadata files is null
+ [SRU] ConfigDrive datasource fails when metadata files is null
** Description changed:
- On Ubuntu 12.04, cloud-init fails to provision when ConfigDrive data has
- a null value for "files":
+ SRU Justification
+ [IMPACT] On Ubuntu 12.04, cloud-init fails to provision when ConfigDrive
+ data has a null value for "files". Instances are DOA.
+
+ [FIX] Cloud-init should check if "files" is a valid value.
+
+ [REGRESSION POTENTIAL] This change is low-risk as it is error-hardening.
+
+ [TEST CASES 1] :
+ 1. Build new images from proposed
+ 2. Boot image on Cloud with files as null
+ 3. Boot image on Cloud with files populated
+ 4. Check to make sure that cloud-init provisioned with out errors
+
+ [TEST CASE 2]:
+ 1. Build existing Ubuntu image on ConfigDrive provisioned cloud
+ 2. Check for any errors in the logs
+ 3. Upgrade cloud-init
+ 4. Reboot and check for errors in logs
+ 5. Create a new instance from existing instance
+ 6. Check for errors in the log.
