If used in conjunction with --csv then you'll get an ever longer CSV file. But you also add either '-n <iterations>' or '--end-time <time>'[1] to make it stop early (or just kill it instead). For example: virt-top -c test:///default --script --csv /tmp/test.csv -n 10 will run for 30 seconds, produce a 11 line (10 measurements + title) CSV file, and then exit. If it _doesn't_ do that, then please file a bug. The virt-top manpage explains all the options in some detail. Rich.
