We are unable to get an IP address when a VM gets launched and the below DHCP error is observed in the Dashboard logs
The setup in done on Fedora 18 using Openstack Grizzly. Its a 2 node setup, with Network+ Controller node having 3 NIC's, and Compute node having 2 NIC's. Tried configuring networking in vlan mode. em1 - mgmt network, em2 - external/public network (br-ex is created on top of this iface) eth1 - internal/data network (br-eth1 is created on top of this iface) ****************** ***************************** plugin.ini ------------- enable_tunneling = False tenant_network_type = vlan network_vlan_ranges = eth1:100:1000 integration_bridge = br-int bridge_mappings = eth1:br-eth1,em2:br-ex ****************** ***************************** The console log from the dashboards is as below. Initializing random number generator... done. Starting network... udhcpc (v1.18.5) started Sending discover... Sending select for 192.168.120.2... Sending select for 192.168.120.2...

Let us know if further information is required to identify the root cause. Some more info, and if someone could possibly identify the root cause then it would be of great help to me. from the tcpdump output , I could track the DHCP discover packet at the tapXXX , qbrXXX , qvbXXX, qvoXX, int-br-eth0, phy-br-eth0 interface, but not after that As per my understanding the flow of packets should be from tapXX -> qbrXX -> qvbXX -> qvoXX --> br-int -> int-br-eth0 -> phy-br-eth0 -> br-eth0 -> eth0 So in this case is there a missing security group rules, which possibly drop the packet. I am not familiar with the iptables rules, so if I need to add any rules could you please help me in adding the rule. -- Regards Gopi Krishna
