Re: [PATCH RFC 0/3] Add checkpoint/restore support to LXC using CRIU
Hi guys,
I marked this series as RFC to discuss some points. I'm interested in
enhancing this specific part of LXC. So, some questions that I would
like to hear as a feedback from community:
1. I decided to use a tar to compress all CRIU img files into a single
file. Any other suggestions?
2. If no is the answer to question above, is there a consensus on
preferring to use command line calls or libraries? I would like to use
libtar for instance. I personally think that this approach is ugly.
Not sure if I'm able to do that. The same for CRIU.
3. Other important opinions obviously.

This patch series implements a way to do checkpoint/restore to LXC driver using
CRIU operations. This respects the other methods to save and restore processes
states: using a file with a header with some metadata. The only difference here
is basically the way LXC drivers join the files produced by CRIU. CRIU generates
a lots of 'img' files and it is compresses using TAR to fit into the libvirt
state file.
