<p>Hi Guys,</p>
<p><br>
</p>
<p>I am writing my master thesis about reducing downtime during live migration. Therefore I also have a look at CRIU and container migration.</p>
<p><br>
</p>
<p>I am using Ubuntu 16.04 as host system and run a Ubuntu 16.04 container on it. In my setup the checkpoint procedure takes ~2sec. During this time all processes are frozen and therefore the downtime accounts to ~2sec, too. I evaluated the code and log files
and I noted that a container is treated as an usual process tree. All processes of this process tree are checkpointed sequentially. On average the checkpoint time of one process was ~170ms and I have 14 processes in total. The question now arises, is it possible
to checkpoint independent processes in parallel? Further, if it is not possible, which dependencies are the reason?<br>
</p>
<p><br>
</p>
<p>Due to the fact that the main focus of my master thesis is on a more general approach, I do not have the time to familiarize myself with the checkpointing code in detail. However, I am personally highly interested in this topic. Hence, I would be very glad
if someone could shed some light on my question.</p>
<p><br>
</p>
<p>Thank you very much for your effort in advance!</p>

<p>Best regards,<br>
