Hardware RNG detected, testing if used properly
[FAILED]

Hardware RNG is present but 'rngd' is not running. No harware random used!

Someone suggest to edit /etc/sysconfig/rngd, add following line

EXTRAOPTIONS="-r /dev/urandom"

Which does not work.

The problem is the rngd-tools installed by the yum would not read the environment file /etc/sysconfig/rngd.

open /usr/lib/systemd/system/rngd.service, add -r /dev/urandom to the ExecStart.

ExecStart=/sbin/rngd -f -r /dev/urandom
