Open Stack

Hi,

I'm able to access the VM console thru the dashboard, on logging in I see
that the instance does not have a public IP address assigned to it.
Also on doing a ifup eth0 -
udhcpc (v1.20.1) started
sending discover ....
sending discover ....
sending discover ....
No lease, failing.

And in the case where I'm first assigning the instance to a private network
and then associating a floating IP, the VM gets a private network IP but
not a public one.

The image I'm using is Cirros-0.3.3.

Any suggestions?

Thanks,
Dhvanan
