From: "Paul E. McKenney" <paulmck@xxxxxxxxxx> When rerunning an old run using kvm-again.sh, the jitter commands will re-use the original "res" directory. This works, but is clearly an accident waiting to happen. And this accident will happen with remote runs, where the original directory lives on some other system. This commit therefore updates the qemu-cmd commands to use the new res directory created for this specific run. Signed-off-by: Paul E.
