Obviously, after a process dies, and is transparently restarted, it might get confused because its pid changed. (This is one of many issues, but I'm starting with pids) I've seen some process checkpointing / migration patches for Linux in the past. Have you had a look around to see if there is anything else that already does this. Perhaps I'm getting the wrong end of the stick but it might save you some time. Basically, all of the existing patches were meant to be just that: patches. My goal is to get everything into the mainline kernel. It turns out that it's much easier to step back and rethink what we need, and recode it to the current kernel standards than try to shoehorn something that exists into shape. Also, many of the existing projects try to do too much in userspace. That said, I'm getting lots of inspiration from existing projects like vserver. -- Dave ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver
Re: [Vserver] Documentation /proc/virtual/*?
Hi ! Is there any documentation of what the various keys and values in the files in /proc/virtual/ mean (more than just a 'ls -R /proc/virtual/*')? The keys (=subdirs) btw are the Context-IDs of the running VServer guest systems. Oh yes, this isn't too hard to find out :) on the first attempt I found this doc: http://linux-vserver.org/HowTo+Read+ProcFS Maybe this helps? No, this is just a cat *. What I want to know is what all those funny values mean, e.g. what do these three columns with 2 values each in cacct mean, what is load_updates, what are the values in limit etc. Thanks in advance.

You are right. I mis-copied-and-pasted. I'll fix that up. It was just
for debugging anyway.
