    Hello,

    Followed your guide but:

    Error: External network 7ecdd64f-2e91-41d1-b177-46fa7940ea87 is not reachable from subnet f8258c5d-32a3-441d-9e73-a13cd0ab9d81. Therefore, cannot associate Port 3daa43d5-47e0-40e5-bcdd-33f220b39580 with a Floating IP. Neutron server returns request_ids: [‘req-b322718e-56be-4d38-bbe2-bd98d74db8b6’]

    Error: Unable to associate IP address 192.168.176.8.

    Any ideas?

    Something went wrong! An unexpected error has occurred. Try refreshing the page. If that doesn’t help, contact your local administrator.

    I am getting this error. [Error: No valid host was found. There are not enough hosts available.] What to do?

      While launching the instance.

      @Sanya,

      Please check with the following command that compute node as enabled and up.

      # nova service-list
      

      If its down, you need to restart the nova-compute service on the compute node and make sure that networking from controller to compute node configured properly. Can you able to ping controller node from compute node?

      Also make that libvirt is up on compute node.

    Hello, thanks for your tutorial, but i have only question, when we are selecting the network for the instances we must select the “external network” ? (Of course what i want to test is external access but when i select the external network on my log i can see a message like this ” ExternalNetworkAttachForbidden: It is not allowed to create an interface on external network “) but if i select internal net when i am creating the instance there is no error but i can’t access to my instance from lan :(
