-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.
+Article moved to https://github.com/xemul/p.haul/wiki/Live-migrating-OVZ-mainstream-container
-== 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.
