When debugging it's useful to stop zdtm.py at certain points and check what's going on out there. For this the --sbs (step-by-step) option is introduced. It will make zdtm.py stop and wait for user keypress before dump, before restore and after restore. Signed-off-by: Pavel Emelyanov <xemul@parallels.com> Acked-by: Andrew Vagin <avagin@virtuozzo.com>
CRIU (Checkpoint and Restore in Userspace)
An utility to checkpoint/restore tasks. Using this tool, you can freeze a running application (or part of it) and checkpoint it to a hard drive as a collection of files. You can then use the files to restore and run the application from the point it was frozen at. The distinctive feature of the CRIU project is that it is mainly implemented in user space.
The project home is at http://criu.org.
