Integration

CRIU is not so easy to be used as a standalone tool -- it works best integrated into other software. This page lists such software and provides details about the current status.

OpenVZ

Status: in progress Currently, vzctl supports CRIU for checkpoint/restore of upstream containers (i.e. when non-OpenVZ kernel is used). Commands vzctl suspend and vzctl restore fully work. Live migration doesn't work yet as it requires support for vzctl suspend {--suspend, --dump, --kill, --restore} which is not yet implemented as it requires a separate daemon to hold the state of a partially checkpointed container (or an ability from criu tool to do that).
