For python developers there exists an easy API to communicate with CRIU. The module sits in lib/py/criu.py
file.
Overview
To use CRIU just create the instance of the criu
class.
Configuring
Specify the way to call CRIU binary by calling one of criu class methods
criu.use_sk(name)
- CRIU is run as service and listens on the socket
name
criu.use_fd(fd)
- CRIU is already spawn and accepts requests on socket
fd
criu.use_binary(path)
- CRIU binary is located in
path
and it will be fork()-ed and execp()-ed
By default the use_binary('criu')
mode is activated.
Specifying options
Use the criu.opts
object to set the RPC options by their regular names
Running
These calls perform CRIU actions
criu.dump()
- Run the dump action
criu.restore()

criu.check()
