<p class="MsoNormal"><span style="font-size:11.0pt">Hi,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">I have installed CRIU (v. 3.6) and run the check. Here are the results:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>

Looks good but some kernel features are missing
which, depending on your process tree, may cause dump or restore failure.” How do I fix this? I run the zdtm test and got “The kernel is tainted:..” Do I get the warning from criu check –all because my kernel is tainted?
<o:p></o:p></span></li></ul>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">I have been trying to checkpoint and restore but at the time of the restore I always get the error: “Error response from daemon: failed to retrieve OCI runtime container pid:…”
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Are the two problems related? I followed the example available here for the checkpointing:
<a href="https://criu.org/Docker">https://criu.org/Docker</a><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">The experimental feature is enabled in both client and server. The checkpoint file is correctly created. However, I have also noticed that the looper in the example does NOT stop after issuing the command
“docker checkpoint create looper checkpoint1”. According to the above guide it should stop, right?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Can you please help me debug this?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">I am running on Ubuntu 18.04 (running via Parallels on MacOS). CRIU version: 3.6. Docker version: “Version: 18.06.1-ce , API version: 1.38”.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
