[ovirt-users] Nginx reverse proxy

I have a physical server that hosts an all-in-one ovirt system. At the time there are only a handful of VMs but I plan to expand (both the number of VMs and the number of physical servers). As I use this for developing / testing various ideas (web apps) I sometimes need to have access directly to VMs from the internet (ports like 80, 443, sometimes others). What I would like is to install a reverse proxy (nginx) in DMZ and get rid of port forwarding system. My question is: is there any way (ovirt, plugin, 3rd party solution) that, when a VM is created, automatically creates the required entries in the reverse proxy so that a preselected +/- customizable list of ports are forwarded to the new VM? Example (where example.com is a preconfigured domain, site3 was the hostname the user entered, 192.168.0.3 is the IP allocated by the DHCP): server { listen 127.0.0.1:443 ssl; server_name site3.example.com; include common.conf; location / { proxy_pass http://192.168.0.3:80; } } And, as a followup: is there a way avoid manually creating an entry in the zone editor on registar's website? Thanks, PP
