rapid (Rapid Automated Performance Indication for Dataplane)
************************************************************
rapid is a set of files offering an easy way to do a sanity check of the
dataplane performance of an OpenStack environment.
Copy the files in a directory on a machine that can run the OpenStack CLI
commands and that can reach the OpenStack public network. Also create a qcow2
image in the same directory with the following characteristics:
* Name of the qcow2 file should be: rapidVM.qcow2
This default name can be overruled on the rapid command line (--image_file)
* Should have DPDK and PROX installed. PROX should be in /root/prox/ directory
* Image should have cloud-init installed
* /mnt/huge should exist to support a command that is executed at startup of the VM: 'mount -t hugetlbfs nodev /mnt/huge'
* Compile prox with 'make crc=soft'. This is a workaround for some cases where the crc calculation offload is not working as expected.
* Compile dpdk to support AESN-NI Multi Buffer Crypto Poll Mode Driver: http://dpdk.org/doc/guides/cryptodevs/aesni_mb.html
Source the openrc file of the OpenStack environment so that the OpenStack CLI
commands can be run:
# source openrc
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 <STACK>.env file containing all info that will be used by runrapid.py
to actually run the tests. Logging can be found in the CREATE<STACK>.log file
You can use floating IP addresses by specifying the floating IP network
--floating_network NETWORK
or directly connect throught the INTERNAL_NETWORK by using the following parameter:
--floating_network NO
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.
It will print test results on the screen while running.
The actual test that is running is described in <TEST>.test.
Notes about prox_user_data.sh script:
- The script contains commands that will be executed using cloud-init at
startup of the VMs.
- The script also assumes some specific DPDK directory and tools which might
change over different DPDK release. This release has been tested with DPDK-17.02.
- 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. Only the [Mx] sections are used as
input for runrapid.py.
