hi all, I'm install openstack using http://docs.openstack.org/havana/install-guide/install/yum/content/nova-network.html guide. When I execute "*nova network-create vmnet --fixed-range-v4=192.168.56.0/24 --bridge-interface=br1 --multi-host=T*" comamnd in controller node, I had this error "*ERROR: The server has either erred or is incapable of performing the requested operation. (HTTP 500) (Request-ID: req-e7fa7707-9e77-4a69-b315-7e9035425350)*" I created br1 on controller node with 192.169.56.1 ip address. I cannot find the reason, Please help me.
