Issue

• I use FindVmByGuid API to inquire the cpu information of vm.
  this is the code:

# API FOR Query VM By Guid
body_hash = {}
body_hash['vmGuid'] = '9a1120bc-d5bc-11e3-9f64-005056b98052'
response = client.request 'FindVmByGuid' do |soap|
    soap.body = body_hash
end

# Convert response to hash
response_hash = response.to_hash
puts "CFME web-service returned: #{response_hash.inspect}"

# Loop through each management system in the array and log the name and guid
response_hash[:find_vm_by_guid_response][:return].inspect

• I have enable the role of collection. and i can see the cpu usage from web uibut the output of cpu_usage and memory_usage is null:

          <cpu_usage xsi:nil="true"></cpu_usage>
          <memory_usage xsi:nil="true"></memory_usage>
