Why does 'virt-who' fail to run on RHEL 7 based RHEV hosts?

Issue

• After installing and configuring virt-who on a RHEL 7 based RHEV host (RHEL-H) as described in article How to configure virt-who in VDSM mode to work with RHEL-H?, virt-who fails to run:

# virt-who --one-shot
Using configuration "satellite.example.com" ("vdsm" mode)
Virt backend 'satellite.example.com' fails with exception:
#

• Running virt-who in debug mode reveals a "sslv3 alert handshake failure" error:

# virt-who --one-shot --debug
