Line 1: − We have the [https://github.com/xemul/p.haul p.haul] project that implements [[live migration]] using CRIU. This page summarizes our experience with live-migrating [http://openvz.org OpenVZ] containers.+ − − == Centos-6-x86_64-devel == − − Need to put container's private on NFS. To do this the /vz should be an NFS mount on both node. E.g. like this − − Container should be created w/o userns support − − # vzctl create 100 --ostemplate=centos-6-x86_64-devel --local_uid=0 --local_gid=0 − − The following BUGs affect migration − − ; Blockers − : https://bugzilla.openvz.org/show_bug.cgi?id=2874 -- init and crond use fsnotify/inotify which will not work on NFS − − ; Would be nice to fix − : https://bugzilla.openvz.org/show_bug.cgi?id=2873 -- killing udev solves the problem, as nobody has files opened on devtmps after it − : https://bugzilla.openvz.org/show_bug.cgi?id=2870 -- you can create a symlink /usr/bin/tar -> /bin/tar inside container to workaround − − Apply [https://gist.github.com/xemul/8601313 these kludges] to p.haul. − − Live migrate a container using − − # p.haul <init-pid> <node2-ip> − − command.
