Execute ``onehost sync --force`` afterwards. This file contains a list of ``:commands`` that will be executed when running the VM monitoring probes. The result of the execution of these commands will appear on the MONITORING section on the VM instance template.

By default an example command is provided, this effectively allows to detect VM crashes
