In case of OpenStack, copy the files in a directory on a machine that can run the OpenStack CLI commands and that can reach the networks to connect to the VMs. You will need an image that has the PROX tool installed. A good way to do this is to use the packer tool to build an image for a target of your choice. You can also build this image manually by executing all the commands described in the deploycentostools.sh. The default name of the qcow2 file is rapidVM.qcow2 When using the packer tool, the first step is to upload an existing CentOS cloud image from the internet into OpenStack. Check out: https://cloud.centos.org/centos/7/images/ You should now source the proper .rc file so Packer can connect to your OpenStack. There are 2 files: centos.json and deploycentostools.sh, allowing you to create an image automatically. Run # packer build centos.json Edit centos.json to reflect the settings of your environment: The following fields need to be the ID's of your system: - "source_image": Needs to be the id of the Centos cloud image - "flavor": Needs to be the ID of the flavor existing in your OpenStack environment that will be used to start the VM in which we will install all tools - "networks": ID of the network that will be used for the VM - "use_floating_ip": true or false - "floating_ip_pool": ID of the floating ip pool in case floating ip are being used - "security_groups": ID of the security group being used Note that this procedure is not only installing the necessary tools to run PROX, but also does some system optimizations (tuned). Check deploycentostools.sh for more details. Now you can run the createrapid.py file. Use help for more info on the usage: # ./createrapid.py --help createrapid.py will use the OpenStack CLI to create the flavor, key-pair, network, image, servers, ... It will create a .env file containing all info that will be used by runrapid.py to actually run the tests. Logging can be found in the CREATE.log file You can use floating IP addresses by specifying the floating IP network --floating_network NETWORK or directly connect through the INTERNAL_NETWORK by using the following parameter: --floating_network NO /etc/resolv.conf will contain DNS info from the "best" interface. Since we are deploying VMs with multiple interface on different networks, this info might be taken from the "wrong" network (e.g. the dataplane network). Now you can run the runrapid.py file. Use help for more info on the usage: # ./runrapid.py --help The script will connect to all machines that have been instantiated and it will launch PROX in all machines. This will be done through the admin IP assigned to the machines. Once that is done it will connect to the PROX tcp socket and start sending commands to run the actual test. Make sure the security groups allow for tcp access (ssh & prox port). It will print test results on the screen while running. The actual test that is running is described in .test. Notes about prox_user_data.sh script: - The script contains commands that will be executed using cloud-init at startup of the VMs. - huge pages are allocated for DPDK on node 0 (hard-coded) in the VM. Note on using SRIOV ports: Before running createrapid, make sure the network, subnet and ports are already created This can be done as follows (change the parameters to your needs): openstack network create --share --external --provider-network-type flat --provider-physical-network physnet2 fast-network openstack subnet create --network fast-network --subnet-range 20.20.20.0/24 --gateway none fast-subnet openstack port create --network fast-network --vnic-type direct --fixed-ip subnet=fast-subnet Port1 openstack port create --network fast-network --vnic-type direct --fixed-ip subnet=fast-subnet Port2 openstack port create --network fast-network --vnic-type direct --fixed-ip subnet=fast-subnet Port3 Make sure to use the network and subnet in the createrapid parameters list. Port1, Port2 and Port3 are being used in the *.env file. Note when doing tests using the gateway functionality on OVS: When a GW VM is sending packets on behalf of another VM (e.g. the generator), we need to make sure the OVS will allow those packets to go through. Therefore you need to the IP address of the generator in the "allowed address pairs" of the GW VM. Note when doing tests using encryption on OVS: Your OVS configuration might block encrypted packets. To allow packets to go through, you can disable port_security. You can do this by using the following commands neutron port-update xxxxxx --no-security-groups neutron port-update xxxxxx --port_security_enabled=False An example of the env file generated by createrapid.py can be found below. Note that this file can be created manually in case the stack is created in a different way (not using the createrapid.py). This can be useful in case you are not using OpenStack as a VIM or when using special configurations that cannot be achieved using createrapid.py.
