Hi, So your DHCP agent is not working as expected. Check if the agent is configured properly and running. The DHCP agent should assign the IP address from private tenant network to the VM. Only then you can connect to it through floating IP.

Also on doing a ifup eth0 - udhcpc (v1.20.1) started sending discover .... sending discover .... sending discover .... No lease, failing. And in the case where I'm first assigning the instance to a private network and then associating a floating IP, the VM gets a private network IP but not a public one. The image I'm using is Cirros-0.3.3. Any suggestions?

I am in the same network as the server but still not able to ping or ssh to the vm. I double checked my networking rules and have configured tcp and icmp properly. Don't really know where this might be breaking. Is there anything else I can do to debug this issue? I also have a installation guide document that I followed, if you want it for reference. - https://docs.google.com/document/d/1hrIjbjIF-nS_Lq6jJTPSeXjz-ZnPG6-OjYm3gEbtvTw/edit?usp=sharing Thanks, Dhvanan On Thu, Aug 6, 2015 at 10:56 AM, Akash Gunjal <akgun...@in.ibm.com> wrote: Hi Dhvanan, Couple of changes are needed in the ifcfg-br-ex file.

I created my network as follows: CREATE NETWORK FOR OPENSTACK 1. a. neutron router-gateway-clear router1 (neutron router-gateway-list) b. neutron subnet-delete public_subnet c. neutron net-delete public d. neutron router-interface-delete router1 private_subnet e. neutron subnet-delete private_subnet f. neutron net-delete private g. neutron router-delete router1 2. a. neutron router-create router1 b. neutron net-create private c. neutron subnet-create --name private_subnet private 192.168.0.0/16 --allocation-pool start=192.168.0.0,end=192.168.255.250 d. neutron router-interface-add router1 private_subnet 3. a. neutron net-create public --router:external=True //(neutron net-create public --router:external) b. neutron subnet-create public 10.16.37.0/24 <set for your n/w> --name public_subnet --enable_dhcp=False --allocation-pool start=10.16.37.230,end=10.16.37.250 <make sure that it will not conflict with other IP address> --gateway=10.16.37.1 <your n/w gateway> c. neutron router-gateway-set router1 public Also I made changes in the ifcfg-br-ex file and ifcfg-<my network> file in /etc/sysconfig/network-scripts. The Changes were as follows: ifcfg-br-ex DEVICE=br-ex BOOTPROTO=static IPADDR=<your workstation IP address> e.g 10.16.37.221 NETMASK=255.255.255.0 DNS1=<your n/w DNS1> e.g 10.16.25.13 DNS2=<your n/w DNS2> e.g 10.16.25.15 BROADCAST=10.16.37.255 GATEWAY=10.16.37.1 NM_CONTROLLED="no" DEFROUTE=yes IPV4_FAILURE_FATAL="yes" IPV6INIT=no ONBOOT=yes TYPE=OVSIntPort OVS_BRIDGE=br-ex DEVICETYPE=ovs ifcfg-p2p1 DEVICE=p2p1 <change with your device name> # HWADDR=00:22:15:63:E4:E2 ONBOOT="yes" TYPE="OVSPort" DEVICETYPE="ovs" OVS_BRIDGE=br-ex NM_CONTROLLED=no IPV6INIT=no There is also a proxy in the network and so for that, I installed by "packstack --allinone --provision-demo=n --provision-all-in-one-ovs-bridge=n". Could someone suggest me a reason as to why i might be facing issues or probably where I can look to debug this issue.
