Test ID: detection_fail_VM_01
Test Title: Detection of failed virtual machine
Tags: performance

Testcase Objective

The objective of this test is to verify how much time is cosumed StarlingX to detect when a Virtual Machine has failed.

Test Pre-Conditions

The StarlingX configuration deployed for this is the Standard Controller (2 controllers + 2 computes) in order to review the behavior in a multinode environment.

Test Steps

1. Launch a VM with the features described below, this section includes an script which could help to do that (Another alternative is to use the OpenStack dashboard).

| Feature    | Description            |
|------------|------------------------|
| RAM        | 2GB                    |
| Disk       | 20GB                   |
| VCPUS      | 1                      |
| Properties | hw:mem_page_size=large |
| Image      | [Debian]               |

Detect the compute where that VM was deployed and kill the QEMU process, immediately after this, the initial time must be taken.
Make a constant of pull request of the VM status and stop the test when it changes.
Finally take the end time and calculate the delta.

Expected Behavior

Result being around 500ms
