CRIU Usage to save and load states
Hi, I came across this forum through a link on CRIU.ORG, so if I'm on the wrong forum, I apologize.
I'm trying to learn how to use criu snapshot/process save state for both playing and debugging video games. I have been trying use it with sample applications such as a text editor, and a random game I downloaded, and even the calculator. I also aim to save and load wine-running applications, but my testing hasn't reached that far. I have not been able to successfully save the state of any application or process, much less load it. I will post a sample of my terminal, with the kind of error I'm receiving. Please let me know of how can I make this work, and maybe name an application or two that it is known to work. I'm currently running Linux Mint 19 Matte.
