Issue

rngd.service fails as does not have enough entropy, predominantly in virtualized environment.
Add package haveged to Red Hat repository so we don't have to use EPEL
When a Red Hat Enterprise Linux OS is running within a virtualized environment (VMWare, etc.) physical devices normally present to generate entropy are not available. This leaves the OS starved for entropy and results in a very small random pool for applications to use, causing application process that require entropy to function to stall.

Environment

Red Hat Enterprise Linux 7
Virtualized environment
