vzmigrate/pvectl migrate openvz containers

Hi,

When using OpenVZ containers, I seem to be unable to migrate a container from one HWN to another, neither using vzmigrate (config file already there), nor pvectl migrate (no shared storage).
This seems to be a severe limitation. vzmigrate in "pure" state has no trouble migrating into blue skies, even live, without any form of shared storage. A working SSH connection and a similar architecture is all it takes.

How can I (live) migrate containers without shared storage using Proxmox?
