Resolution

• Configure /etc/virt-who.d/virt-who.conf with the correct information as follows:

# vi /etc/virt-who.d/config.conf
[config]
type=<hypervisor_type>
server=<vcenter/esx host>
username=<vcenter/esx_username>         >> VCenter FQDN
password=<password>                     >> Vcenter admin password  
owner=<owner>
env=Library
rhsm_hostname=<satellite hostname>
rhsm_username=admin                    >> Vcenter admin User
rhsm_encrypted_password=<encypted-password>
rhsm_prefix=/rhsm
hypervisor_id=hostname
filter_hosts=host1.example.com,host2.example.com OR
exclude_hosts=host1.example.com,host2.example.com

Note: Ensure the "username" has a read-only role set and is not an "admin" user otherwise you'll get the error message 'Cannot complete login due to an incorrect user name or password.'

• Start the virt-who service:

 # systemctl start virt-who
