Doc Type: Enhancement
Doc Text:
Feature: The administrator will see a detailed report when a VM was not started for scheduling reasons. The report contains the filter that was responsible for removing each candidate host from the candidate list. Reason: Our users were confused when a complicated situation in the cluster prevented them from starting a VM. Result (if any): engine.log contains detailed information and the popup error dialog contains the detailed report as well.

Comment 1 Doron Fediuck 2013-09-11 16:15:59 UTC 
The way it will work is by aggregating the filters inputs and outputs,
and provide the whole list when there are no hosts to run on.
