Comment 9 for bug 1627371

I was also affected by this problem, which I solved by adding extra RAM and cores. However, in some cases, when working with virtual machines, this problem might be exacerbated by the fact that VMs are much slower in collecting entropy with respect to real hardware. The low entropy slows down /dev/random, which may cause a sensible delay for cryptographic software (https://developers.redhat.com/blog/2017/10/05/entropy-rhel-based-cloud-instances/).

In one of my old installations of FreeIPA, the kadmin server used to take several minutes to start. I solved this problem installing a daemon for generating entropy ("haveged", in my case). With haveged, the same daemon which used to take minutes, was starting in a fraction of a second.
