[CRIU] [PATCH 0/4] Process Migration using Sockets

[Katerina Koukiou]

This patch series is a rebased version of these three patches
https://lists.openvz.org/pipermail/criu/2015-December/024218.html

together with one extra error checking patch.

The current patch allows CRIU to perform in-memory remote live migrations.
Snapshot images are stored in memory and sent to a remote node, where they are
stored in memory until the process is restored. This can be activated by using
'--remote' in the command line arguments for launching CRIU
Dump/Pre-Dump/Restore.
