action #135035
Updated by mkittler 5 months ago
## Motivation
Multi-machine jobs have been failing since 20230814, because of a misconfiguration of the MTU/GRE tunnels. A workaround
has been found in forcing the complete multi-machine tests to run in the same worker.
The purpose of this ticket is to have all multi-machine runs be scheduled on the same well-configured worker.
The change doesn't need to be permanent but it does need to be applied until proper networking between multi-machine nodes can
be guaranteed.
## Acceptance Criteria
* **AC1:** If configured accordingly all nodes of a multi-machine job must be scheduled to run on the *same* worker
## Suggestions
* Have a look at https://github.com/Martchus/openQA/pull/new/dependency-pinning for how this could be enabled and documented.
