A system misconfiguration that prevents qemu from running at all (for example, a missing dynamically linked library) will keep the console.log file from the previous run. This can fool the developer into thinking that this failed run actually completed correctly. This commit therefore overwrites the console.log file just before launching qemu. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>

# 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 minutes qemu-args boot_args
|
|
#
|
|
# qemu-args defaults to "-enable-kvm -soundhw pcspk -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.
