The main idea is to be able to operate with container at the moment where its processess and resources are already restored but the processes are not yet in running state, ie just before we kick them. Beside the need of tuning up beancounters (which is vz7 specific feature) this might be useful to make some additional debug tests from the script. We can't reuse ACT_POST_RESTORE action or move it because we can kill the restored processes here and resume them on a source side as avagin@ explained. [ xemul: In between POST_RESTORE and PRE_RESUME ghost files are cleaned up (an a little bit more), so two separate stages are required and the latter one cannot fail. ] travis-ci: success for Add "pre-resume" stage Signed-off-by: Cyrill Gorcunov <gorcunov@openvz.org> Signed-off-by: Pavel Emelyanov <xemul@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.
Pages worth starting with are:
- Kernel configuration, compilation, etc
- A simple example of usage
- More sophisticated example with graphical app
