Problems with VM network

Hi everyone. I have issues with networking of the instances. I'm running openstack (nova, glance, dashbord) in a single server configuration. I used https://github.com/elasticdog/OpenStack-NOVA-Installer-Script/raw/master/nova (https://github.com/elasticdog/OpenSta...) - for Nova installation (glance, dashboard - manual install). For the reason that I can add images to Glance from command line, and then could run instances in Dashboard from added images I could suggest that all is installed properly. The VM instances state are "Running". After all i find out that I couldn't connect to my instances. Where I can start finding what is wrong with network?

Your DHCP start ends in .10 but nova is assigning .2+ You will probably have to either switch the start address to .2 or edit the database and set reserved=1 for .2 - .9 so nova doesn't give them out.
