Steps to Reproduce:
1.Create the hardware spec for the pass-through from the original hardware spec
2.Open the pass-through's hardware spec,go to "Create New Pass-Through Certification" and click "select a parent cert entry"
3.If the original hardware spec have both supplemental cert and original cert,you can see both of them are listed there,please see the attachment.
Since the original cert and supplemental cert have the same VMM,we cann't differentiate them so we don't know which one should be used to create the pass-through.
I think only the original certs should be listed there.
