For scenarios that do not specify the number of CPUs, this can result in kvm.sh wastefully scheduling only one scenario at a time even when the --kconfig argument would allow a number to be run concurrently. This commit therefore makes kvm.sh consider the --kconfig arguments when scheduling scenarios across the available CPUs. Signed-off-by: Paul E.
