[ovirt-users] Hardering oVirt Engine

Hello, we are subject to PCI-DSS. I have some questions. We currently have setup oVirt in our environnement. We created 2 Datacenter. - one with a cluster with hosted engine on gluster (Hyperconverged env) which represents the "LAN" part - one with a cluster with gluster storage wich is the DMZ In PCI-DSS we have to secure communication (use HTTPs as much as possible). I did saw that ovirt-ha-agent (on hosted-engine capable host) check the status of the engine by sending GET request on the hosted-engine on port 80 (the same check that hosted-engine --vm-status did in fact). Since ovirt 4.2.2, with the introduction of gluster eventing, a new flow (HTTP post resquest) is needed from gluster nodes to the engine. (In my case, it's a flow from the DMZ to the LAN part in HTTP (non secure) Here is my question. Is it possible to "hardering" this part of the engine ? Another question out of PCI scope. Events like warning and error in the dashboard are clean each days. I tried to find which process did that (look into /etc/cron.daily, root crontab, etc) on the engine without succes. Is there any maintenance task that is run periodicaly ? Could we have the list of all the engine's task ? (regulary check the status of host, vm, storage) also the frequency ? I would appreciate the help. (Great great product ovirt !) Thank you for your jobs ! We did manage KVM hypervisor as standalone machine without all the power that libvirt provides. No need to spend lot of money into licencing product (VSphere and co)
