    <br>
    At the moment in oVirt there are no database changes. The code that
    you are looking at is a POC. We (the community) still need to
    address the database changes.I think that prior to adding the
    database changes we should first add a REST client that can
    communicate with the Quantum service (at the moment this is done via
    the Quantum CLI). I have a short list of items that need to be
    addressed for a a basic Quantum integration (this will at least give
    us the infrastructure to build on in the future). I think that for
    the first phase we should support the following:<br>
    <br>
    &nbsp;&nbsp;&nbsp; - oVirt Engine will support one Quantum service (the instance
    currently supports only 1 plugin)
    <br>
    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; - oVirt installation will have Quantum service as a
    dependency
    <br>
    &nbsp;&nbsp;&nbsp; - All hosts in a cluster must have the same networking support.
    This can be one of the following:
    <br>
    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; - Legacy oVirt networking
    <br>
    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; - Legacy oVirt networking for management and Quantum for VM
    networking
    <br>
    &nbsp;&nbsp;&nbsp; - When a VDSM host is registered (IP, password etc), one of the
    above methods will registered. If this Quantum, then the relevant
    configuration data will be sent to VDSM. Agent packages will exist
    on VDSM
    <br>
    &nbsp;&nbsp;&nbsp; - If a logical network is assigned to a Quantum cluster then
    this network must be registered with Quantum (to get the UUID)
    <br>
    &nbsp;&nbsp;&nbsp; - All VM's running on this cluster will receive a port ID and
    pass an attachment ID to the Quantum
    <br>
    &nbsp;&nbsp;&nbsp; - Limitations:
    <br>
    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; - No network statistics for logical quantum networks
    <br>
    <br>
    I think that small secluded changes can help the integration - for
    example:-<br>
    &nbsp;&nbsp;&nbsp; - implement a REST client (used to communicate with Quantum
    service)<br>
    &nbsp;&nbsp;&nbsp; - update database to store relevant quantum ID's<br>
    &nbsp;&nbsp;&nbsp; - improve VDMS support for Quantum code (have a plugin
    architecture - so that different technologies can plug their code
    into VDSM)<br>
    &nbsp;&nbsp;&nbsp; - address HOST management<br>
    &nbsp;&nbsp;&nbsp; - packaging<br>

    </blockquote>
    <br>
    Please note that this is a POC. All of the data generated by the
    script is persistent - that is, it is stored in the /tmp directory.
    I am not really sure that I understand your question. If oVirt
    engine crashes then the user will not be able to deploy VM's. If the
    Quantum service crashes then the user should not be able to
    configure Quantum networks or attach ports etc. <br>
    If the quantum service crashes or is unreachable by VDSM then a
    newly deployed VM may not be able to "attach" to the Quantum
    network. This can be averted by having the following - on oVirt
    engine there should be a process that monitors the status of the
    Quantum service. If this is down then it should restart it. This can
    and should be discussed in more detail.<br>

    <br>
    My thinking is that when a VNIC of a VM is linked to a Quantum
    network then the Quantum port should be created. After some
    discussion I understand that the oVirt VNIC has a UUID - this can
    now be used as the attachment ID. In my opinion the Quantum
    interface should be limited to the host management. The rest should
    be "hidden" from the user.<br>

              You have asked a very interesting and good question.
              Please see the answers an explanations below. Both flow
              are used. The "a" flows (1a2a and 3a) are for the network
              management. The "b" flows (1b and 2b) are for the VM
              management.<br>
              Network management (1a):<br>
              &nbsp;&nbsp;&nbsp; - user create a Quantum network<br>
              &nbsp;&nbsp;&nbsp; - user will create a Quantum port and attachment<br>
              VM Management (1b):<br>
              &nbsp;&nbsp;&nbsp; - users creates a VM<br>
              &nbsp;&nbsp;&nbsp; - assigned VM to one or more logical networks. Each
              each assignment will receive the above quantum details<br>
              VM flow:<br>
              &nbsp;&nbsp;&nbsp; - VDSM creates the libvirt XML file<br>
              &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; - (2b) if libvirt version is 0.9.10 or earlier
              then VDSM will have to create the tap device (via
              attachment ID) and will set it with type 'ethernet' in the
              libvirt file (this is what was done in the POC). In
              addition this it need to notify OVS of the VM ID on the
              port<br>
              &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; - in later versions of libvirt, libvirt will do
              the create via the attachment id <br>
              &nbsp;&nbsp;&nbsp; - VDSM will start the VM<br>
              Network flow (2a and 3a):<br>
              &nbsp;&nbsp;&nbsp; - The Quantum agent polls the Quantum plugin for
              network changes. If the agent detects a tap device that is
              part of a network then it will configure the
              characteristics of this tap device on the OVS. In the case
              of the POC it will be the VLAN tag of the network<br>

                                      A bit of background regarding the
                                      script. The purpose of the POC was
                                      to show that Quantum can be run in
                                      oVirt. It would have been ideal to
                                      write a REST client that could
                                      interface with the Quantum
                                      service. Due to the fact that I
                                      was not familiar with the oVirt
                                      code I felt that a quicker and
                                      more productive means was to
                                      invoke a bash script from the
                                      oVirt engine code. The script
