Description of problem:
Issues when trying to print the attribute family from an ESX hypervisor. We are not populating this information, then the code will fail.

Version-Release number of selected component (if applicable):
6.14

How reproducible:
100%

Steps to Reproduce:
1. Create a custom report template
—
<%- load_hosts().each_record do |host| -%>
<%- report_row(
'Name': host.name,
'custom': host.operatingsystem.family,
) -%>
<%- end -%>
<%= report_render -%
—
2. Try to generate the report
3.

Actual results:
If the customer doesn't have "virt-who-hyper..." entries, it will be fine. If they have already virt-who, it will fail.

Expected results:
Generate the report, independent if the virt-who entries are around.
