Hi,

This is a known issue and I assume this will be never be fixed. If you want to use Debian you can think of switching to Proxmox VE which is based on Lenny (1.9) or Squeeze (2.0 beta). We are using the stable RHEL6 OpenVZ kernel so you have a good chance to get chkp/restore running.
There is only one issue with our init.logger patch, but if you disable it everything should work, live-migration etc.

See http://pve.proxmox.com and especially, http://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_Len ny
