[PATCH v2 2/3] kunit: tool: Allow overriding the shutdown mode from qemu config

[Thomas Weißschuh]

Not all platforms support machine reboot.
If it a proper reboot is not supported the machine will hang.
Allow the QEMU configuration to override the necessary shutdown mode for
the specific system under test.
