- Increase qemu-1-setup.sh timeout to 20min since it sometimes fails to complete after 15min. - Timestamp all qemu-1-setup.sh lines to look for hangs. - Add a 'watchdog' process to print out the top running process every 30sec to help with debugging. Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Tony Hutter <hutter2@llnl.gov> Closes #17714
