[ovirt-users] Disable SSL for ovirt-ha-broker?

I have a neglected oVirt 4.3 cluster that consists of two hosts with a hosted engine. Unfortunately, the host SSL certificates on both hosts are expired, and now the hosted engine is down from a power loss event. I don't see a way to get ovirt-ha-broker functioning again if the vdsm certificates are expired, since I can't get the hosted engine VM to start in order to generate new host certificates. My sledgehammer approach was to just disable SSL in the configuration for vdsm and libvirt, but I can't seem to figure out how to disable SSL for ovirt-ha-broker. Is this possible? I don't know what else to try. I figure if I can just get the hosted-engine back up, and I can maybe proceed with getting one of the hosts back up and functional in some way, and maybe getting the single VM that I am concerned about started up. If the hosted engine isn't recoverable, is it possible to get another VM up and running with just standard kvm/libvirt/virsh if I still have access to the storage?
