Comment 1 Rehana 2014-08-19 13:53:44 UTC 

Actual results:
subscription "Awesome OS Server Basic" is attached on the system, but the system is already healed by the "Awesome OS Super Hypervisor" (guest-limit =-1) subscription

Expected results:
subscription "Awesome OS Server Basic" is not actually needed on the system, 
as the "hypervisor" subscription is capable of making the  product " Awesome OS Server Bits" compliant

I can see similar behavior. I will investigate further.
Comment 3 Filip Nguyen 2015-09-18 10:30:50 UTC 
I confirm this is an issue. The auto-attach logic will always suggest only those pools which combined with already consumed subs will be compliant with the guest_limit. This means that in your case it will only suggest those that combined with awesomeos-guestlimit-4-stackable will be guest_limit compliant. 

Even though this seems like rather severe issue (I can think of several scenarios where current auto-attach fails completely), there is no easy fix for this so I will lower priority on this bug.

In case this hits a customer, it is important that he firstly manually attaches some sub that will cover guest_limit. After that auto-attach will work fine.
