** Description changed:

- I've got confirmation that the chassis_asset_tag DMI value is a hard-
- coded identifier for the Azure platform (both Azure and Azure Stack (the
- on-premise variant of Azure)).
+ === Begin SRU Template ===
+ [Impact]
+ Azure identifies itself to guests by setting providing a well known value in
+ the chassis asset field of dmi data.  This is done both in Azure public cloud
+ and in Azure Stack (the on-premise variant of Azure).
+ 
+ By checking for this value cloud-init can more quickly identify whether
+ or not it is running on Azure.
+ 
+ [Test Case]
+  - Launch an instance, enable proposed, upgrade.
+  - Clean instance and re-boot
+    $ rm -Rf /var/lib/cloud /var/log/cloud-init*
+    $ rm -f /etc/cloud/cloud.cfg.d/91_walinuxagent.cfg  # bug 1700769
+    $ reboot
+ 
+  - ssh back in look around
+    - check for 'WARN' in /var/log/cloud-init*
+    - look in /run/cloud-init/ds-identify.log.  It should say:
+       Found single datasource: Azure
+ 
+  - reboot, ssh back in and verify all still good.
+ 
+ 
+ [Regression Potential]
+ Instances running in Azure or Azure Stack that did *not* have this value
+ would not be identified as Azure.  We have been told by representatives
+ from Microsoft that that will not be the case.
+ 
+ [Other Info]

+ === End SRU Template ===

+ 
+ I've got confirmation that the chassis_asset_tag DMI value is a hard-coded 
identifier for the Azure platform (both Azure and Azure Stack (the on-premise 
variant of Azure)).
  
  $ cat /sys/class/dmi/id/chassis_asset_tag
  7783-7084-3265-9085-8269-3286-77
  
  The detection logic in both ds-identify and Azure ds should be updated
  to use this value.
