I do not know about the Load Balancer, but after some "research", I 
found and executed as root:

systemctl stop vboxdrv.service
systemctl start vboxdrv.service

This had no effect -- but these may be the wrong commands. (Evidently, 
on EL 7, systemctl replaces the usual rc scripts.)  Any other suggestions?
