'rngd' in RHEL does not detect hardware random number generators in Intel IvyBridge processors or later
Issue
Modern Intel CPUs (Ivy Bridge and later) come with a hardware random number generates, as seen by rdrand in /proc/cpuinfo's flags. However, the rngd command Red Hat Enterprise Linux (RHEL) 5 and RHEL 6 do not detect or use it.
Is Red Hat planning to address this?
