Hi,
I finally could fix my vnet account, so I can add my 5 cents ...
Entropy and random number generation is one of the more obscure Linux topics.
It is under much debate and the code related to it gets changed between kernel
versions.
Some even consider the concept of entropy pools using up

Described in:

on a z990 and z890. Maybe that
needs to go

What happens in you install rng-tools
What happens in you install rng-tools and start the service (assuming this is a

Hi,
At a point during SLES15 SP2 release, an update to the kernel switched to
the new crng random number generator. This is causing the random number
generator to take 2 minutes

We have haveged on our sles 15 SP2 servers. We didn't consciously put it
