Hi all,
I followed the instructions in https://github.com/mseknibilel/OpenStack-Folsom-Install-guide/blob/stable/GRE/OpenStack_Folsom_Install_Guide_WebVersion.rst, but there is something wrong with network connnectios of the virtual machine, I can't ping the virtual machine, neither the private ip nor the public ip.
The public ip of my virtual machine is 202.122.38.16 and the floating ip associated with it is 192.168.23.103, see below:
root@controllernode:~# quantum floatingip-list
+--------------------------------------+------------------+---------------------+--------------------------------------+
| id                                   | fixed_ip_address | floating_ip_address | port_id                              |
+--------------------------------------+------------------+---------------------+--------------------------------------+
| 3d94c4d9-c6b4-4401-aec4-cbbe39369663 | 202.122.38.16    | 192.168.23.103      | 3831791a-a284-48c8-b219-7482fd7536fa |
| ecb7dbee-f9f7-4198-9461-658d177ee6d6 | 202.122.38.15    | 192.168.23.102      | 4bb1c620-e2be-4803-92e2-321ae9b7dad5 |
+--------------------------------------+------------------+---------------------+--------------------------------------+
in the controller node ,the route information is:
root@controllernode:~# route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
default         192.168.23.1    0.0.0.0         UG    0      0        0 eth0

in the network node, the route information is :
root@networknode:~# route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
default         192.168.23.1    0.0.0.0         UG    0      0        0 br-ex

and in the network node, the bridge informaion can be shown here:
root@networknode:~# brctl show
bridge name     bridge id               STP enabled     interfaces
br-ex           0000.842b2b74e328       no              em1

                                                        tapccb52561-49
