Testcases for services failover

- keepalived restart # 4756965
- keepalived stop # 3385682

Changes:
- RallyManager refactored to use updated rally container with tempest
- Added 'rally.create_rally_task' and 'rally.run_task' methods to
  generate load on the OpenStack cluster with the specified task config
- new mark for test cases that configure 'rally' fixture:
  @pytest.mark.with_rally(rally_node=<str>,
                          prepare_openstack=<bool>,
                          prepare_tempest=<bool>)
- a new method common_services_deployed.check_keepalived_pillar()
  to check the keepalived pillar settings consistency
- a new fixture 'func_name' returns the current test function name
- a new method 'underlay.get_target_node_names(target='ctl')' to get
  a list of all nodes which name starts with the specified target string
- a new method underlay.delayed_call() which can postpone the specified
  shell command to run in several minutes later in the background
  on the specified node
- fixture 'grab_versions' now works also for failed tests

Contribute

Please send patches using gerrithub.io:

git remote add gerrit ssh://review.gerrithub.io:29418/Mirantis/tcp-qa
git review

Clone the repo

git clone https://github.com/Mirantis/tcp-qa
cd ./tcp-qa

Install requirements

pip install -r ./tcp_tests/requirements.txt
  • Note: Please read [1] if you don't have fuel-devops installed, because there are required some additional packages and configuration.

Get cloudinit image

wget https://cloud-images.ubuntu.com/xenial/current/xenial-server-cloudimg-amd64-disk1.img -O ./xenial-server-cloudimg-amd64.qcow2

Choose the name of the cluster model

LAB_CONFIG_NAME variable maps cluster name from the model repository with the set of templates in the ./tcp_tests/templates/ folder.

export LAB_CONFIG_NAME=virtual-mcp-ocata-dvr  # OVS-DVR with ocata packages
export LAB_CONFIG_NAME=virtual-mcp-ocata-ovs  # OVS-NO-DVR with ocata packages
export LAB_CONFIG_NAME=virtual-mcp-ocata-cicd  # Operational Support System Tools
export LAB_CONFIG_NAME=virtual-mcp11-dvr  # OVS-DVR with neutron packages
export LAB_CONFIG_NAME=virtual-mcp11-ovs  # OVS-NO-DVR with neutron packages
export LAB_CONFIG_NAME=virtual-mcp11-dpdk  # OVS-DPDK with neutron packages

Set packages repository

Note: The recommended repo is testing. Possible choices: stable, testing, nightly. Nightly contains latest packages.

export REPOSITORY_SUITE=testing

Run deploy test

export IMAGE_PATH1604=./xenial-server-cloudimg-amd64.qcow2
export SHUTDOWN_ENV_ON_TEARDOWN=false  # Optional

LC_ALL=en_US.UTF-8  py.test -vvv -s -k test_tcp_install_default

Run deploy test and rally verify (tempest)

export IMAGE_PATH1604=./xenial-server-cloudimg-amd64.qcow2
export SHUTDOWN_ENV_ON_TEARDOWN=false  # Optional

LC_ALL=en_US.UTF-8  py.test -vvv -s -k test_tcp_install_run_rally

Run OSS deploy

export IMAGE_PATH1604=./xenial-server-cloudimg-amd64.qcow2
export SHUTDOWN_ENV_ON_TEARDOWN=false  # Optional

LC_ALL=en_US.UTF-8  py.test -vvv -s -k test_oss_install_default

Run deploy test for mk22-qa-lab01 (outdated)

Note: This lab is not finished yet. TBD: configure vsrx node

export ENV_NAME=tcpcloud-mk22  # You can set any env name
export LAB_CONFIG_NAME=mk22-qa-lab01  # Name of set of templates
export VSRX_PATH=./vSRX.img           # /path/to/vSRX.img, or to ./xenial-server-cloudimg-amd64.qcow2 as a temporary workaround

LC_ALL=en_US.UTF-8  py.test -vvv -s -k test_tcp_install_default

, or as an alternative there is another test that use deploy scripts from models repository written on bash [2]:

LC_ALL=en_US.UTF-8  py.test -vvv -s -k test_tcp_install_with_scripts

Labs with names mk22-lab-basic and mk22-lab-avdanced are deprecated and not recommended to use.

Use HugePages for environments based on qemu-kvm VMs

To create VMs using HugePages, configure the server (see below) and then use the following variable:

export DRIVER_USE_HUGEPAGES=true

Configure HugePages without reboot

This is a runtime-based steps. To make it persistent, you need to edit some configs.

  1. Remove apparmor
service apparmor stop
service apparmor teardown
update-rc.d -f apparmor remove
apt-get remove apparmor
  1. Allocate memory for Hugepages

2Mb * 30000 = ~60Gb RAM will be used for HugePages. Suitable for CI servers with 64Gb RAM and no other heavy services except libvirt.

WARNING! Too high value will hang your server, be carefull and try lower values first.

echo 28000 | sudo  tee  /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages
apt-get install -y hugepages
hugeadm --set-recommended-shmmax
cat /proc/meminfo | grep HugePages
  1. Mount hugetlbfs to use it with qemu-kvm
mkdir -p /mnt/hugepages2M
mount -t hugetlbfs hugetlbfs /mnt/hugepages2M
  1. Enable HugePages for libvirt
echo "hugetlbfs_mount = '/mnt/hugepages2M'" > /etc/libvirt/qemu.conf
service libvirt-bin restart

Create and start the env for manual tests

dos.py create-env ./tcp_tests/templates/underlay/mk22-lab-basic.yaml
dos.py start "${ENV_NAME}"

Then, wait until cloud-init is finished and port 22 is open (~3-4 minutes), and login with root:r00tme
