Hello, based on the 3D below, it seems that the most logical way to add support for container live migration to libvirt is to integrate the latter with CRIU. If I understand it correctly, Daniel's suggestion below would be that of - 1st converting CRIU to a library - 2nd making libvirt use that library to C/R the container/s CRIU has recently announced support for CRIU as a service and the reason why they opted for a service instead of a library [1] seems to be associated with a use case they had: ability for an application to invoke a self-dump C/R In Libvirt's case it would not be the container to ask for a self dump, but it would be libvirt itself to orchestrate it. In light of the new CRIU as a service feature, is libvirt's preference still that of using a library? Would a service be equally good? Is there anyone actively working or looking at this (libvirt+CRIU)?

Hi,
I am new to this community and am not much aware of current status libvirt work for LXC.
Currently I am evaluating LXC with libvirt. and I found still many features like checkpoint/restore/live migration ,
Checkpoint/restore/migration is something we'd have to delegate to the CRIU code (http://criu.org/LXC). I'm not sure how easy that is todo though, since CRIU code is not a nicely reusable library, it is a set of command line tools. This will need some investigation. I don't believe anyone is actively working on it.
Please, feel free to contact CRIU development team (https://lists.openvz.org/mailman/listinfo/criu).
We are open for discussion and will help with integration.
