Load-Testing VM Migration with MTV

Changes

2024-08-02: variable added: provision_data_file. Defaults to ./provision_data.yaml 2024-09-01: -e count=N allows to you run fewer users than the total in provision_data 2024-09-10: datastore automatically detected from provision_data.yaml 2024-09-10: datastore id looked up from VMware

Prerequisites

Setting Up Provision Data for your target cluster

• Deploy a multi-user virt roadshow catalog item

• Get the provision_data dict from the Babylon output and save it to ./provision_data.yaml

  • You can find the provision data in the YAML tab of ResourceHandle of your order.

    

    Note	Make sure to get all the users from the provision_data yaml in the manifest. The playbook will use them and their auth credentials to login to the OCP cluster provider.

Install requirements.yml

Use your favorite python virtual environment manager to install the requirements.

I use pyenv with pyenv-virtualenv

1. pyenv virtualenv migration_test

2. pip install ansible

3. ansible-galaxy role install -r requirements.yml

4. or for newer ansible versions use ansible-galaxy collection install -r requirements.yml

Run the playbook

The playbook searches for ./provision_data.yaml and uses that to authenticate as each user to the cluster.

ansible-playbook ./playbook_multi.yml

You can also indicate a different provision_data_file:

ansible-playbook ./playbook_multi.yml -e provision_data_file=./provision_data2.yaml

You can limit the number of users created with -e ceiling=10:

ansible-playbook ./playbook_multi.yml -e ceiling=10

Cleanup

1. First try deleting everything, but only setting the plans to Archived=true, per the docs. I don’t see how it actually really cleans up anything, but I like to be a good citizen.

   ansible-playbook ./delete_all.yaml -e delete_plans=false -e provision_data_file=./provision_data2.yaml

2. Second, the Plans will not go away in Archived=true mode, so run the playbook again, with delete_plans=true

   ansible-playbook ./delete_all.yaml -e delete_plans=true -e provision_data_file=./provision_data2.yaml
