Here is a list of results in attempts to checkpoint/resume containers with vzctl + criu bundle running on vanilla 3.13 kernel. Note the tests were done with Andrey Vagin patches applied to vzctl: "hook_ct: remove the non-working with devpts", "hook_ct: bind mount the host /dev directory in CT". Also the vz configs require LOCAL_UID="0" and LOCAL_GID="0" (also no net features were used).

Here is a list of results in attempts to checkpoint/resume containers with vzctl + criu bundle running on vanilla 3.13 kernel. Note the tests were done with Andrey Vagin patches applied to vzctl: "hook_ct: remove the non-working with devpts", "hook_ct: bind mount the host /dev directory in CT". Also the vz configs require LOCAL_UID="0" and LOCAL_GID="0" (also no net features were used).
