2	# vm-test-install.sh — boot the just-built Mountaineer ISO in a fresh
3	# disposable target VM and drive the installer non-interactively.

5	# Usage:
6	# tools/qemu/vm-test-install.sh [<config-yaml>]
7	#
8	# <config-yaml> defaults to tools/qemu/test-install.yaml — the installer's
9	# --config schema for unattended install. The target VM is destroyed and
10	# recreated each run, so this is safely re-runnable.
