[openstack-dev] [rally] Rally scenario for network scale with VMs

I created a new scenario which scales on network and VM at same time.
If you have no objection I would like to send out a review this week
I actually have following reviews to do next week

  1.  Scenario for network stress I.e VM+ network with subnet with unique cidr. So in future we can add a router to this and do apt-get update from all Vms and test network scale
  2.  Scenario for booting Vms on every compute node in the cloud….This has a dependency right now this is admin access. So for this I need Item 3
  3.  Provide an ability to make rally created users have admin access for things like forced host scheduling . Planning to add this to user context
  4.  Iperf scenario we discussed

If you have objection to these I can submit reviews for these. Have the code need to write unit tests for the scenarios since looking at other reviews that seems to be the case

Sorry for long reply.

At this point Rally supports only benchmarking from temporary created users and tenants.

Fortunately today we merged this Network context class: https://review.openstack.org/#/c/103306/96
it creates any amount of networks for each rally temporary tenant.

So basically you can use it and extend current benchmark scenarios in rally/benchmark/scenarios/nova/ or add new one that will attach N networks to created VM (which is just few lines of code). So task is quite easy resolvable now.

Best regards,
Boris Pavlovic

Is there  a Rally scenario under works where we create N networks and associate N Vms with each network.
This would be a decent stress tests of neutron
Is there any such scale scenario in works
I see scenario for N networks, subnet creation and a separate one for N VM bootups
I am looking for an integration of these 2
