Live migration using CRIU

p.haul

Process HAULer -- a tool to live-migrate containers and processes

The live-migration idea is quite simple. To live migrate a task one needs to

• stop it and save its state into image file(s)
• make images available on the remote host
• recreate task on it from the images

This is what p.haul does. It heavily uses CRIU (http://criu.org) to do state dump and restore. Task's stopped time is decreased using the CRIU's pre-dump action.

Get p.haul ready

1. Install criu or put criu binary location to $PATH.

2. Install protobuf-compiler and python-protobuf packages.

3. Get the sources and run:

$make

This will generate rpc_pb2 and stats_pb2 python modules from rpc.proto and stats.proto.
