I am trying to deploy devstack in Dell R910 with Ubuntu 12.04 as host OS. 
I installed devstack in the scripted manner as mentioned in 

My intention is to create CentOS VMs with following property.
1. VMs should be able to ping each other
2. VMs are accessible by ssh from any host in 10.135.0.XX network
3. VMs should be connected to open internet.

To do this I am following the All-In-One: Dedicated Hardware method 
mentioned in http://devstack.org/guides/single-machine.html

My localrc contains the following
condor at r910:~/devstack$ cat localrc
disable_service n-net
enable_service q-svc
enable_service q-agt
enable_service q-dhcp
enable_service q-l3
enable_service q-meta
enable_service quantum
# Optional, to enable tempest configuration as part of devstack
enable_service tempest


Route information of the host
condor at r910:~/devstack$ route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use 
Iface         UG    100    0        0 
eth1   UG    0      0        0 
eth0 U     0      0        0 
eth1     U     1000   0        0 
eth0 U     0      0        0 
br-ex   U     0      0        0 
virbr0   U     0      0        0 

Devstack External Gateway interface of the router is in DOWN state. Pls 
fined the attached screen shot. 

How can I make it ACTIVE state? What is the wrong I am making? 

Thanks for any help.
