Ubuntu:22.04 build fails #2314

Open tzvetkovg opened 11 months ago

tzvetkovg commented 11 months ago

I am running on a macOS and I know criu requires linux so that's why I try to build criu via a docker container. My steps are as follows

Steps to reproduce the issue:

  1. docker run --privileged --rm -it -v /var/run/docker.sock:/var/run/docker.sock ubuntu:22.04 bash
  2. Then inside the container I run this to install sudo - apt-get update && apt-get install sudo
  3. Kernel check inside the container returns uname -a Linux f5d30f4b834a 6.5.11-linuxkit #1 SMP PREEMPT Mon Dec 4 11:30:00 UTC 2023 aarch64 aarch64 aarch64 GNU/Linux
  4. Inside the container then I install criu - sudo apt-get install criu
  5. criu check and I get 
    Error (criu/util.c:635): exited, status=1
Error (criu/util.c:635): exited, status=1
Warn  (criu/kerndat.c:869): Can't keep kdat cache on non-tempfs
Looks good.

    6.sudo criu check --all

    Error (criu/util.c:635): exited, status=1
Error (criu/util.c:635): exited, status=1
Warn  (criu/kerndat.c:869): Can't keep kdat cache on non-tempfs
Warn  (criu/cr-check.c:855): Dirty tracking is OFF. Memory snapshot will not work.
Warn  (criu/cr-check.c:1284): Do not have API to map vDSO - will use mremap() to restore vDSO
Error (criu/cr-check.c:1250): UFFD is not supported
Error (criu/cr-check.c:1250): UFFD is not supported
sudo: mon_handle_sigchld: waitpid: No child processes
Error (criu/cr-check.c:1038): failed to mount autofs: No such device
Warn  (criu/cr-check.c:1204): CRIU built without CONFIG_COMPAT - can't C/R compatible tasks
Looks good but some kernel features are missing
which, depending on your process tree, may cause
dump or restore failure.

    7.Then I am trying to build the simple example as described here https://criu.org/Simple_loop

  6. the dump command works fine inside the docker container (criu dump -t 2221 -vvv -o dump.log && echo OK)
  7. However, it fails on restore command criu restore -d -vvv -o restore.log && echo OK with the exception

Eventually, I would like to do docker checkpoint so I've tried the steps from inside the ubuntu container here after I've installed criu https://docs.docker.com/engine/reference/commandline/checkpoint/

  1. docker run --security-opt=seccomp:unconfined --name cr -d busybox /bin/sh -c 'i=0; while true; do echo $i; i=$(expr $i + 1); sleep 1; done'
  2. docker checkpoint create cr checkpoint1 but I got Error response from daemon: Cannot checkpoint container cr: runc did not terminate successfully: exit status 1: CRIU version check failed: exec: "criu": executable file not found in $PATH path= /var/run/desktop-containerd/daemon/io.containerd.runtime.v2.task/moby/c42152766e1b23cb28b6899de0eb074633158dc3368b6f1cccb5054edaaec3e5/criu-dump.log: unknown

so not sure, is it to do with the docker container or the fact I am running from macOS? Is there any official example how to run criu from a macOs through a docker container? None of the examples I followed actually work..

adrianreber commented 11 months ago

I don't really understand your setup. But CRIU is Linux only and unfortunately Ubuntu ships a broken version of CRIU. That will always fail.

Not sure about your docker problems. Sounds like CRIU is simply not installed.

tzvetkovg commented 11 months ago

is there any linux docker container with criu example that runs fine in macOS?

adrianreber commented 11 months ago

I don't know. Never used macOS. But if you are looking for a Linux distribution with a working version of CRIU. Anything but Ubuntu.

znley commented 11 months ago

MacOS is not Linux, It seems that your run a ubuntu:22.04 container on macos. Maybe your need a real linux kernel.
