Public bug reported: In the Instance object, on a remotable operation such as save(), we refresh the pci_devices and security_groups with the information we get back from the database. Since this *replaces* the objects currently attached to the instance object (which might be backlevel) with current versions, an older client could get a failure upon deserializing the result.
We need to figure out some way to either backport the results of remoteable methods, or put matching backlevel objects into the instance during the refresh in the first place. ** Affects: nova Importance: Medium Assignee: Dan Smith (danms) Status: Confirmed ** Tags: unified-objects -- You received this bug notification because you are a member of Yahoo!
