    <div class="moz-cite-prefix">Hello,<br>
      <br>
      Now I got successfully booted instances with attached network. But
      network still is not working. DHCP service doesn't assign fixed IP
      to instance so I addet it manualy. I assign floating IP to that
      instance. When I ping floating IP host is unreachable. With
      tcpdump in XenServer I can see this:<br>
      <br>
      15:04:30.683155 IP 10.10.50.230 > 10.10.50.231: GREv0, key=0x1,
      length 50: ARP, Request who-has 10.5.5.4 tell 10.5.5.1, length 28<br>
      15:04:30.683303 IP 10.10.50.232 > 10.10.50.231: GREv0, key=0x1,
      length 50: ARP, Request who-has 10.5.5.4 tell 10.5.5.1, length 28<br>
      15:04:31.683108 IP 10.10.50.230 > 10.10.50.231: GREv0, key=0x1,
      length 50: ARP, Request who-has 10.5.5.4 tell 10.5.5.1, length 28<br>
      15:04:31.683243 IP 10.10.50.232 > 10.10.50.231: GREv0, key=0x1,
      length 50: ARP, Request who-has 10.5.5.4 tell 10.5.5.1, length 28<br>
      <br>
      10.10.50.230 is neutron host's guest networks IP<br>
      10.10.50.231 is XenServer guest network's IP<br>
      10.10.50.232 is other XenServer network IP, I don't know why it
      appears there.<br>
      10.5.5.4 is instances fixed IP.<br>
      <br>
      So as I can check network works like: internet -- neutron host --
      XenServer -- instance<br>
      And it fails somewhere between XenServer and instance, I am not
      strong with OVS, but I think problem is somewhere with OVS
      configuration.<br>
      <br>
      "ovs-vsctl show" in XenServer: <a
        href="http://paste.openstack.org/show/57462/">http://paste.openstack.org/show/57462/</a><br>
      Integration bridge is xapi4<br>
      I got two instances, both have integration networks attached and
      can ping each other.<br>
      <br>
      OVS plugin agent's configuration in nova-compute:<br>
      <br>
      [ovs]<br>
      tenant_network_type = gre<br>
      tunnel_id_ranges = 1:1000<br>
      enable_tunneling = True<br>
      integration_bridge = xapi4      # Integration bridge in XenServer<br>
      tunnel_bridge = br-tun<br>
      local_ip = 10.10.50.231         # Guest network's IP in XenServer<br>
      <br>
      Also I turned off firewall driver in ovs plugin agent's
      configuration:<br>
      firewall_driver = neutron.agent.firewall.NoopFirewallDriver<br>
      <br>
      Thanks.<br>

        I am going forward with trying to implementing neutron in

        But there is one catch, in section, where you enable
        services(ENABLED_SERVICES) there is two more services, which
        isn't in havana release: q-agt and q-domua. So, if I am right,
        this two services make possible to run necessary neutron
        commands from domU in to dom0. So, where I can get this
        services? Or maybe all this is included in
        neutron-plugin-openvswitch-agent package, just need to configure
        it right?<br>
        In /etc/neutron/rootwrap.conf is xenapi section, so I suppose
        that it is required to run neutron + XenServer. And there is
        /usr/bin/neutron-rootwrap-xen-dom0 script, which login to
        XenServer and run commands.<br>
        <br>
        And additional question:<br>
        <br>
        Is anyone trying to live migrate with OpenStack + neutron +
        XenServer setup? I can't live migration, got error: <a
          moz-do-not-send="true"
          href="http://paste.openstack.org/show/55683/">http://paste.openstack.org/show/55683/</a><br>
        Maybe this is because my neutron setup is not working
        completely, but maybe this is bug in live migration ...<br>
        <br>
        Thanks.<br>

                  At least something is going forward! :) That works, no

                  I created network in XenServer by command:<br>

                  <br>
                  I get bridge name - xapi1<br>
                  <br>
                  After that in XenServer:<br>
                  <br>
                  ovs-vsctl add-br xapi1<br>
                  <br>
                  Got error: ovs-vsctl: cannot create a bridge named
                  xapi1 because a bridge named xapi1 already exists<br>
                  <br>
                  In nova-compute I changed integration_bridge to xapi1
                  in ovs_neutron_plugin.ini file. Than in nova-compute i
                  run:<br>

                  ovs-vsctl del-br br-int<br>
                  ovs-vsctl add-br xapi1<br>
                  <br>
                  Now running instances get br-int network attached, but
                  lookls like dhcp is not working. Instance can't assign
                  IP. Neutron and nova logs without errors. Maybe is
                  some ideas why dhcp is not working? Maybe some there
                  is some "painful spots" with dhcp? Or I missed
