Dear Hutson,

I suppose that you are using OpenNebula 3.0. That bug was fixed in the
master branch for the next release. This bug appears when the VM pool
is empty or no CPU is defined in the VMS. You can fix it applying the
following patch:

diff --git a/src/authm_mad/remotes/quota/quota.rb
b/src/authm_mad/remotes/quota/quota.rb
index 1f13234..26336bb 100644
--- a/src/authm_mad/remotes/quota/quota.rb
+++ b/src/authm_mad/remotes/quota/quota.rb

             resources.each{ |res|
                 pool = get_pool(res, user_id)
                 base_xpath = "/#{res}_POOL/#{resource}"
+                usage[key] ||= 0
                 Quota.const_get("#{res}_USAGE".to_sym).each { |key, params|
                     pool.each_xpath("#{base_xpath}/#{params[:xpath]}") { |elem|
                         if elem
-                            usage[key] ||= 0
                             if params[:count]
                                 usage[key] += 1
                             else


Kind regards.
