Dear All,

I setup the openstack on the a ubuntu12.04 laptop (not VM), I have NIC wlan0 wifi interface ( The localrc file indicate that (correct me if i am wrong)

the floating range is fixed range = flat_interface =wlan0 (not sure if should be wlan0 or eth0, but I am using wlan 0 to internet)

After I installed the devstack, I have two accounts, admin and demo. Thus, I login with both account,

From Admin, I can see two network public: (my floating range in localrc) and private (fixed range in localrc) and all instances created will be automatically assigned with a ip from this public network (like

From demo account, I can only see on network which is private, and all instance created will be assigned with a private ip, like

Why that ?

So, when I was on admin account, I use nova command to list the floating ip, but they said there is not floating ip defined and I list nothing. But, when I use nova-manage floating-ip create te flotaing ip range ( and want to get one from the pool (like and when I wanted to assign this 240 ip to the instance, it was failed. I use nova floating-ip-bulk-list and it still shows nothing ....

any idea ?

The only goal so far is to make the instance access from outside and ping google. by assigning the floating ip. BTW, anytime instanced created no mater which account I used, there is not ip on the eth0 using ifconfig, but from the horizona GUI console, I can see the ip allocated. Can anyone tell me what I should do to do this ?

Thanks very much for any comment,
