Hi,
I've discovered an issue which I don't understand. On a new test install
of EL9 I saw this message in the logs:
Mar 01 08:09:18 <hostname> pcp-pmie[2870]: Low random number entropy
available 15.6%avail@xxxxxxxxxxxxxxxxxxx
This is on a 64 core "AMD Opteron(tm) Processor 6282 SE" server but I also
got the same low entropy on an EL9 KVM guest running on a "AMD EPYC 7601"
server.
After a lot of searching the net I understand that rng has been reworked
in 5.x kernels and /proc/sys/kernel/random/entropy_avail reaches only 256
in default configurations. But why does it go too low on a test system
with almost not load?
Is this an issue with AMD CPUs or does it also happen on other systems?
Thanks for any insights,
Simon
