Description of problem:
-----------------------
I ran into this issue while verifying https://bugzilla.redhat.com/show_bug.cgi?id=1497733.

I provisioned a service with a few VMs. On the SUI, CPU, Memory, and Storage Utilization do get displayed for the individual VMs, but when I navigate away from the page and then navigate back to the page, all the Utilization data was gone.


Version-Release number of selected component (if applicable):
-------------------------------------
5.9.0.8


How reproducible:
----------------
Always


Steps to Reproduce:
--------------------
1.Manage a provider
2.Provision a service with VMs.
3.Enable C&U collection for the provider.


Actual results:
---------------
VM Utilization data disappears after after navigating away from page.


Expected results:
-----------------
VM Utilization data should always be displayed so long as C&U data for the VM is available in the metric_rollups table.
