Title: Include error message in instance faults Status in OpenStack Compute (Nova): Fix Released Status in OpenStack Compute (nova) folsom series: Fix Released Bug description: When nova compute throws an exception while trying to create a vm instance, information about the exception is put into the "instance_faults" database table. That table has a message column. That column is getting filled in with the exception class name and not with the exception message. Here is a little more detail of what I am trying to do: I want to have my application that is using OpenStack to be able to show the root cause of why OpenStack could not create a vm. I do a "nova boot ..." call to create a vm instance. If that fails to get created properly I want to display the reason back to the user. I was expecting that I would be able to get a message with the cause when I did a "nova show vm-name" call. That call contains fault information. Without this bug fix I get information like this: | fault | {u'message': u'RemoteError', u'code': 500, u'created': u'2012-05-11T20:19:41Z'} The 'RemoteError' is the class name of the exception that was thrown. Instead I would like to get an error line like this: | fault | {u'message': u'Zero floating ips available.', u'code': 500, u'created': u'2012-05-11T20:19:41Z'} The "Zero floating ips available" is the message that the RemoteError exception contains. The instance_faults table has a code, message, and details columns (along with some others). For the case I have they get filled in like this: message: RemoteError code: 500 details: RemoteError: Zero floating ips available followed by the full stack trace I don't want to have to parse out the message from the stack trace, so the details field will not help me. I am hoping that OpenStack can change the message field in the database to be one of two things: 1. the exception message only. For example: "Zero floating ips available" 2 the class name followed by the exception message. For example: "RemoteError: Zero floating ips available" With one of those changes I will be able to get the error message that explains why the vm was not created with the REST call that does the equivalent of the "nova show vm-name" command and show the message to the user so they will know what went wrong. I have attached a patch file that shows the change in the nova/compute/manager.py file for option 1 To manage notifications about this bug go to: https://bugs.launchpad.net/nova/+bug/1013350/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : yahoo-eng-team@lists.launchpad.net Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
