There is a popup if you leave the mouse cursor on the highlighted entry box. It's the same as for other policies. Is that enough or do we want something fancier?

This popup says nothing about the parameters (just displaying the same parameter name ...) and their relations to other parameters , I had found that not only that I don't know what the parameters means but also I do not know how other parameters are affected by changing its value ....
The parameters are described on the feature page http://www.ovirt.org/Features/Even_VM_Count_Distribution. If there is a request to add it to gui, we'll need to involve UI designer.
Please see the BZ description , main problem here is that the values are dependent and if you put 'wrong' values you got no clue how to fix that apart of a red rectangle on the values fields ...

No, the allowed values for the field doesn't depend on values in other fields. In your case the problem is, that the values for MigrationThreshold and SpmVmGrace can't be lower than 5 which is clear from the regexp shown as the help text: "HighVmCount" : "^([0-9][0-9]*)$", "MigrationThreshold" : "^([5-9][0-9]*)$", "SpmVmGrace":"^([5-9][0-9]*)$"
