# Run a kvm-based test of the specified tree on the specified configs.
# Fully automated run and error checking, no graphics console.
#
# Execute this in the source tree.  Do not run it as a background task
# because qemu does not seem to like that much.
#
# Usage: kvm-test-1-run.sh config builddir resdir seconds qemu-args boot_args
#
# qemu-args defaults to "-enable-kvm -nographic", along with arguments
#			specifying the number of CPUs and other options
#			generated from the underlying CPU architecture.
# boot_args defaults to value returned by the per_version_boot_params
#			shell function.
#
# Anything you specify for either qemu-args or boot_args is appended to
# the default values.  The "-smp" value is deduced from the contents of
# the config fragment.
#
# More sophisticated argument parsing is clearly needed.
