I know where is the problem but I dont know yet how to fix it : - Quantum creates TAP interface on ESSEX-2 - From ESSEX-2, I can't ping VMs on ESSEX-1 Here my ovs_quantum_plugin.ini : [DATABASE] sql_connection = mysql://ovs_quantum:password@10.68.1.40:3306/ovs_quantum [OVS] integration-bridge = br-int [AGENT] root_helper = sudo Do we need enable bridge ?
