The --remote option and image cache/proxy implementation have been deprecated in favour of criu-image-streamer.
CRIU can use this option to migrate applications over the network.
Remote[edit]
Add the --remote option to send the checkpoint data through the network and restore the application on a different machine.
The communication is performed as follows: At the src_node, CRIU dump sends the images through UNIX sockets to Image Proxy. Image Proxy sends them to Image Cache via a TCP connection. At the dst_node, Image Cache forwards the images via UNIX sockets to CRIU restore.
CRIU usage example with --remote:
dst_node# criu image-cache -d --port <port> src_node# criu image-proxy -d --port <port> --address <dst_node> src_node# criu dump -t <pid> --remote dst_node# criu restore --remote
Image Cache[edit]
The option's syntax is image-cache -d --port <port>.
Image Proxy[edit]
The option's syntax is image-proxy -d --port <port> --address <dst_node>.
