[Users] oVirt 3.3 and Neutron

Dear oVirt users. I'm trying to setup oVirt 3.3 using an OpenStack Neutron existing service as network provider. It works pretty well: I can use the networks defined in Neutron, import them and when I launch VM instances from oVirt they get an internal-IP address from Neutron. A can also associate a floating IP to the Neutron port and get inbound connectivity for the virtual machine. The problem is that if I shutdown the VM (both from inside the VM itself and from the oVirt WEB GUI) the association port/internal-IP/floating-IP is lost and when the VM is booted again It will get a different internal-IP on a different port and I have to manually re-associate the floating-IP. Is there a way to keep the IP addresses when the VM is simply shutted down and not deleted? This is the behavior when using OpenStack: if I poweroff the VM, the IPs are kept for the future. Moreover: can you confirm that in oVirt 3.3 there is still no support for the Neutron security rules? Thank you very much Best Regards Riccardo
