Open Stack

I lanch an instance, but the instance has not IP when I run command
  'ip addr'.But router has assign ip for it.

  My environment is:
  two vms in virtualbox
  each vm has two ethernet, 192.168.5.0/24 use bridge network; 10.0.0.0/24 use nat network, both is ok
  I lanch provider network, and router ip is 192.168.5.203, I can ping it on the host.
  openstack instance has got an ip,192.168.5.205, I can see it in network top0loy of the dashboard, and I can see provider network port is up,but I can't ping it.

  Please forgive me if this question is too simple, since I'm newbie to
  openstack. And I lack of method to fix problem, If anynoe can give me
  ideas，I'll be very appreciate.
