As of Virtuozzo 7, CRIU is fully integrated and supported. Older OpenVZ releases used in-kernel checkpoint/restore functionality, now superseded by CRIU.

It would be nice to have bash (or other shell) to launch criu with <code>--restore-sibling</code> option and get new kid processes from it. Right now we workaround it with "[[shell jobs]]".

The [https://openjdk.java.net/projects/crac/ CRaC] (Coordinated Restore at Checkpoint) Project researches coordination of Java programs with mechanisms to checkpoint (make an image of, snapshot) a Java instance while it is executing. Restoring from the image could be a solution to some of the problems with the start-up and warm-up times. The primary aim of the Project is to develop a new standard mechanism-agnostic API to notify Java programs about the checkpoint and restore events. Other research activities will include, but will not be limited to, integration with existing checkpoint/restore mechanisms and development of new ones, changes to JVM and JDK to make images smaller and ensure they are correct.
