When running 'cirt x dir rss' one will see the way pagemap chunks are scatered across the VMs of processes. Sample output from the env00 zdtm test is 22 400000 / 1 00400000 / 5 /root/criu/test/zdtm/static/env00 604000 / 2 00604000 / 1 /root/criu/test/zdtm/static/env00 00605000 / 1 /root/criu/test/zdtm/static/env00 853000 / 1 00853000 / 33 7faba2d4b000 / 6 7faba2d4b000 / 4 /usr/lib64/libc-2.22.so 7faba2d4f000 / 2 /usr/lib64/libc-2.22.so 7faba2d51000 / 2 7faba2d51000 / 4 7faba2d54000 / 1 ~ 7faba2f64000 / 3 7faba2f64000 / 3 7faba2f74000 / 1 7faba2f74000 / 1 7faba2f75000 / 2 7faba2f75000 / 1 /usr/lib64/ld-2.22.so 7faba2f76000 / 1 /usr/lib64/ld-2.22.so 7faba2f77000 / 1 7faba2f77000 / 1 7fffb4de3000 / 3 7fffb4de2000 / 70 7fffb4e24000 / 2 ~ 7fffb4e27000 / 1 ~ 7fffb4f6a000 / 2 7fffb4f6a000 / 2 Signed-off-by: Pavel Emelyanov <xemul@virtuozzo.com> Signed-off-by: Andrei 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.
Pages worth starting with are:
- Kernel configuration, compilation, etc
- A simple example of usage
- More sophisticated example with graphical app
