Hello Timur,

I have one question, so I am testing rally boot and delete scenario, it seems to work fine when tenant is 1 and user is 1. Although if I change tenant to 2 and users 2, I see below error. Any idea why this can happen ?

cat boot-runcommand-delete.json

                }

            }

        }

    ]

}

Hi Ajay,

looks like you need to use NeutronContext feature to configure Neutron Networks during the benchmarks execution.
We now working on merge of two different comits with NeutronContext implementation:
https://review.openstack.org/#/c/96300  and https://review.openstack.org/#/c/103306

could you please apply commit https://review.openstack.org/#/c/96300 and run your benchmarks? Neutron Network with subnetworks and routers will be automatically created for each created tenant and you should have the ability to connect to VMs. Please, note, that you should add the following part to your task JSON to enable Neutron context:
...
"context": {
    ...
    "neutron_network": {
        "network_cidr": "10.%s.0.0/16",
    }
}
...

Hope this will help.

Hi
I am trying to run the Rally scenario boot-runcommand-delete. This scenario has the following code
 def boot_runcommand_delete(self, image, flavor,
                               script, interpreter, username,
                               fixed_network="private",
                               floating_network="public",
                               ip_version=4, port=22,
                               use_floatingip=True, **kwargs):
  server = None
        floating_ip = None
        try:
            print "fixed network:%s floating network:%s" %(fixed_network,floating_network)
            server = self._boot_server(
                self._generate_random_name("rally_novaserver_"),
                image, flavor, key_name='rally_ssh_key', **kwargs)

            self.check_network(server, fixed_network)

The question I have is the instance is created with a call to boot_server but no networks are attached to this server instance. Next step it goes and checks if the fixed network is attached to the instance and sure enough it fails
At the step highlighted in bold. Also I cannot see this failure unless I run rally with –v –d object. So it actually reports benchmark scenario numbers in a table with no errors when I run with
rally task start boot-and-delete.json

And reports results. First what am I missing in this case. Thing is I am using neutron not nova-network
Second when most of the steps in the scenario failed like attaching to network, ssh and run command why bother reporting the results
