Run KVM Resiliency Test.
Requires a specific KVM environment (virtual hard drive), see KVM SR for more
informations.
Scenario:
1/ Boot from a custom image
2/ The VM from the main instance starts a simple get/set server. It will receive a random number sent from the resiliency test. The VM will store this number, and the test suite will store the number as well.
3/ Resilience is done, wait XX seconds
4/ For each clone: do a takeover. Check that IPv6 of new main instance is different. Check, when doing a http request to the new VM that will fetch the stored random number, that the sent number is the same.
Note: disk image is a simple debian with the following python code running at boot:
import os
from flask import Flask, abort, request
app = Flask(__name__)
storage = 'storage.txt'
@app.route("/")
def greeting_list(): # 'cause they are several greetings, and plural is forbidden.
return "Hello World"
@app.route("/get")
def get():
return open(storage, 'r').read()
@app.route("/set")
def set():
if os.path.exists(storage):
abort(503)
open(storage, 'w').write(request.args['key'])
return "OK"
if __name__ == "__main__":
app.run(host='0.0.0.0', port=80)
"""
slap = slapos.slap.slap()
slap.initializeConnection(server_url, key_file, cert_file)
