we need to review this issue and increase the entropy on the hosts.

Hi,

We do, ever since we had low entropy slowing down engine builds. Lago is running on physical hosts, so I think its less relevant there. We might need to make OST deploy it in the VMs it uses though, or perhaps have Lago provide an RNG device if it isn`t already. -- Barak Korren RHV DevOps team , RHCE, RHCi Red Hat EMEA redhat.com | TRIED.
