Re: [Openstack-operators] [Rally] Scale testing of openstack

If you have multiple networks, you have to define the one you want used. You can define it in the json.

In the args you need to add a nics block, that defines the net-id of the network you need.

Hi Dina,
Thanks for the reference.

I edited the sample boot.json file and added the network context. It gives an error while executing the task: "Error BadRequest: Multiple possible networks found, use a Network ID to be more specific". I think because I have multiple networks, its asking for which network to select.

JSON file:

{

"NovaServers.boot_server": [

{

"args": {

"flavor": {

"name": "m1.tiny"

},

"image": {

"name": "cirros-0.3.4-x86_64"

}

},

"runner": {

"type": "constant",

"times": 4,

"concurrency": 2

},

"context": {

"users": {

"tenants": 3,

"users_per_tenant": 2

},

"network": {

"networks_per_tenant": 2,

"subnets_per_network": 1

}

}

}

]

}

Can you please help me with this issue ?

Thanks,

Akshay

Akshay,

you may try to use http://docs.openstack.org/developer/rally/plugin/plugin_reference.html#novaservers-boot-server-scenario and specify two contexts in the scenario configuration: user context for tenant creation and network context for networks creation for these tenants. Scenario itself will be creating the VMs and link them to the networks.

Cheers,

Dina

Hi,
I have a openstack setup with 1 controller node, 1 network node and 2 compute nodes. I want to perform scale testing of the setup in the following manner:

- Create 10 tenants

- Create 1 router per tenant

- Create 100 neutron networks across 10 tenants attached to the router

- Create 500 VMs spread across 10 tenants attached to the networks

Individually, I can create tenants, routers , networks ,vms , but I don't know how to keep them interconnected meaning the networks connecting to those existing router and then VMs connecting to those networks.

Please suggest me if some plugin is already available and how to generate load from those VMs

Thanks,

Akshay Sanghai
