The iso boot may get stuck in CI on errors in kickstart post install section. 

The problem is that the ci_phase_iso_boot.sh uses "parallel" to execute scenarios and "parallel" expects all the child processes to exit to consider the job finished.

Since we're using `--erroronfail` option in kickstart %post section, the installation is halted by anaconda displaying the %post logs on the console (probably using `more` command or its like). One needs to manually scroll until the end of %post output so that the installation continues to the eventual shut down of the system.

Note: removing `--erroronfail` %post option is not possible because errors are then ignored and the process finishes successful even in case of %post script failures.

4.16 and below

100%

1. Add "exit 1" in the %post kickstart section
2. Run ci_phase_iso_boot.sh

The ci_phase_iso_boot.sh script gets stuck when errors are encountered in a VM %post section.

The ci_phase_iso_boot.sh script should finish with errors after the `--wait` timeout of virt-install call in scenario.sh is exceeeded.
