I used icehouse release. I can create floating IPs useing nova-manage floating create, and I laso can check the floating ip list using nova-manage floating list.

But when I allocate flaoting ip using nova floating-ip-create command,it returns error like this: ERROR: FloatingIpPoolNotFound: Floating ip pool not found. (HTTP 404) (Request-ID: req-5f47f447-b92e-4380-8ee9-5acfcda9e10f)

I want to know why and how to deal with it.

You must create a externel Network first:

# neutron net-create ext-net --shared --router:external=True

# neutron subnet-create ext-net --name ext-subnet \
  --allocation-pool start=FLOATING_IP_START,end=FLOATING_IP_END \

The allocation-pool is your Floating-IP Pool

Of course u can but only as admin

Go to Networks under the Admin panel

  1. +Create Network
  2. Name: Extern/Provider/Whatever
  3. Project: Admin
  4. Provider Network Type: What you have set as br_ext e.g. Vlan/Flat/Local ...
  5. Set: Shared and External
  6. Finish

ahh then you must create the subnet in this new Network! Same as normal Networks!

Now I can bind a flaoting ip to a vm, but I can not ping the floating ip from other PC.

Do you have configure your ext-br correctly ? Have you set your OVS bridge correctly ?
