Yes, the issue was the lack of entropy. haveged on a VM works but the quality of its entropy is still debated. A better solution is to use the paravirtualized VirtIO RNG device. We already have it on the first boot; we are working to ensure it's always there also after the engine imported the engine VM: https://gerrit.ovirt.org/#/c/62334/ > > But now the question arises, in what cases can be a helpful > ovirt-warmup.service (https://github.com/geertj/ > ravstack/blob/master/share/ovirt-warmup.service) ? > > 03.10.2016, 12:32, "Sandro Bonazzola" <[email protected]>: > > This looks like not enough entropy on the host / guest running > ovirt-engine. > > If you're on Hosted Engine I suggest to install haveged (in EPEL repo) > and run it to ensure enough entropy is available for the VM. > > Adding Simone. > -- IMPORTANT!
