Second step – dumping VE. At this stage CPT saves the state of processes and global state of VE to an image file. All the process private data needs to be saved: address space, register set, opened files/pipes/sockets, System V IPC structures, current working directory, signal handlers, timers, terminal settings, user identities (uid, gid, etc), process identities (pid, pgrp, sid, etc), rlimit and other data. This stage can be done with:

vzctl chkpnt VEID --dump --dumpfile <path>
