Can not pass images_dir_fd option when using pycriu

[prenit-wankhede]

When trying to use pycriu to dump a python process, it is throwing error

import os
from pycriu.criu import criu

c=criu()
f = os.open("dummy", os.O_DIRECTORY)
c.opts.images_dir_fd = f
c.use_binary("/home/ec2-user/criu/criu/criu/criu")
c.dump()

python does not allow getting file descriptors for directories and then write files in that directory.

Has anyone use pycriu library and successfully dumped the process?

Please help.

Please do not add the same question to multiple tickets.

Take a look at p.haul which uses pycriu: https://github.com/checkpoint-restore/p.haul/
