Hi Britt, Thanks for the answer.
I am using Virtual machine(KVM) for openstack installation. Its a single node installation. Now i can create instance from openstack dahboard and and can login in to the instance from dashboard konsole. But i couln't connect to instance from controller node. Also i couldn't have connection between instances. Ifconfig output from openstack installation node ======================= root@ubuntu:/home/geo# ifconfig br-int Link encap:Ethernet HWaddr 26:73:95:7a:c5:4e inet6 addr: fe80::ec9d:9aff:fe2f:66ab/64 Scope:Link UP BROADCAST RUNNING MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:8 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:648 (648.0 B) br-tun Link encap:Ethernet HWaddr 0e:af:b2:8e:89:44 inet6 addr: fe80::c89f:cfff:fe74:712/64 Scope:Link UP BROADCAST RUNNING MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:8 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:648 (648.0 B) eth0 Link encap:Ethernet HWaddr 52:54:00:d6:4c:4f inet addr:192.168.122.54 Bcast:192.168.122.255 Mask:255.255.255.0 inet6 addr: fe80::5054:ff:fed6:4c4f/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:162 errors:0 dropped:3 overruns:0 frame:0 TX packets:100 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:16187 (16.1 KB) TX bytes:13445 (13.4 KB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:737 errors:0 dropped:0 overruns:0 frame:0 TX packets:737 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:104803 (104.8 KB) TX bytes:104803 (104.8 KB) tap561bdedf-3e Link encap:Ethernet HWaddr 42:c5:72:1c:3b:99 inet6 addr: fe80::40c5:72ff:fe1c:3b99/64 Scope:Link UP BROADCAST RUNNING MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:8 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:648 (648.0 B) tapde436ec7-3b Link encap:Ethernet HWaddr b6:09:88:dc:f7:5a inet6 addr: fe80::b409:88ff:fedc:f75a/64 Scope:Link UP BROADCAST RUNNING MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:8 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:648 (648.0 B) ====================================== Same eth0 i have used to add br-ex, you mean thats the issue right?
