I was actually unaware that criu has been packaged already, so this is very good news. There are more userspace utilities to land, like vzlist, vzpid, etc, but those will be bundled in the vzctl package itself. As for actually enabling the kernel config options for CRIU in the kernel, we talked about that yesterday at FUDCon. I need to discuss this with the kernel team still, but a tentative idea is to enable it in rawhide debug kernels to start with and see how things go from there. That's 3.7 based at the moment. I've resisted enabling it so far because namespaces aren't completed yet and it depends on those. It's also hidden behing CONFIG_EXPERT, which I _really_ don't want to enable because it makes the kernel configs a mess. Well, there is a bunch of patches still in flight to give criu the ability to CR whole containers. But this is moving very fast. =) -- Sent from my Atari. -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel

I was waiting until the kernel has enabled the necessary options. Without those options enabled the package does not make much sense. Once it is enabled I still plan to submit crtools for review.

Hey, can I interest you in supporting the interfaces listed here with openvz? http://www.freedesktop.org/wiki/Software/systemd/ContainerInterface This improves intergration of systemd with the container logic, and makes sure SELinux doesn't choke on the container, and journalctl -m on the host works fine.

You can submit it for review right away noting that it isn't expected to be functional. Others can review the spec meanwhile. Work can move forward in parallel. We have done that before.
