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