Hi Vish

Here is the ifconfig output of *compute node*

br100     Link encap:Ethernet  HWaddr 00:50:56:b2:01:5f
          inet addr:10.10.10.3  Bcast:10.10.10.255  Mask:255.255.255.0
          inet6 addr: fe80::c895:59ff:fe29:f708/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:16 errors:0 dropped:0 overruns:0 frame:0
          TX packets:66 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:1646 (1.6 KB)  TX bytes:4194 (4.1 KB)
vnet0     Link encap:Ethernet  HWaddr fe:16:3e:00:91:2c
          inet6 addr: fe80::fc16:3eff:fe00:912c/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:16 errors:0 dropped:0 overruns:0 frame:0
          TX packets:81 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:500
          RX bytes:1870 (1.8 KB)  TX bytes:5820 (5.8 KB)
And here is the output of brctl show

*bridge name     bridge id               STP enabled     interfaces
br100           8000.005056b2015f       no                eth1

        vnet0
*
the virtual machine ip address is = 10.10.10.5

1) I can ping this ip from compute node but from controller node I can't
ping this.
2) But on controller node there is not any br100, brctl show nothing here
is the ouput of ifconfig of controller node

eth0      Link encap:Ethernet  HWaddr 00:50:56:b2:01:58
          inet addr:63.55.xx.38  Bcast:64.22.82.127  Mask:255.255.255.128
          inet6 addr: fe80::250:56ff:feb2:158/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:3136 errors:0 dropped:0 overruns:0 frame:0
          TX packets:2636 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:941305 (941.3 KB)  TX bytes:1173739 (1.1 MB)

eth1      Link encap:Ethernet  HWaddr 00:50:56:b2:01:5e
          BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
