the heat engine works slow compared with the direct provisioning engine

[Sergey Kolekonov]

This bug was detected during integration tests execution. If we provision two equal clusters with direct engine and heat engine, the 'heat' cluster's state changes to "Active" 10-20 minutes later compared with the 'direct' cluster.

When we use the direct engine, we use Nova client to associate a floating IP address with an instance. But when we use the heat engine, Heat uses Neutron client to associate a floating IP address. Then we poll Nova to get the floating IP address and use it to configure a cluster. The problem is that Nova gets information about the floating IP address associated with the instance after 10-20 minutes if the IP was associated using the Neutron client.

For example, this is the console log of integration tests, and the only difference between them is the provisioning engine:

 Thanks Sergey! Bad to know that...
I just wanted to mention that this bug is found in other projects as well https://bugs.launchpad.net/tempest/+bug/1262529.

Also we can crate a workaround in the code, to poll not nova VMs directly, but port list and grep floating ip in instance by its private ip, but we shoudl change the polling part in way to use neutron client instead of nova

    Speed up of Heat provisioning via Neutron

    * This fix adding one more attempt for checking of assigned floatingIP
      via neutron.
    * If nova returned instance id w/o floating ip assigned savanna tries to
      find it in floating IPs assosiated with port assigned to this
      instance.
    * This patch speed up Heat engine when neutron used up to 20 mins
