checkpointing doesn't work with PPP enabled containers (based on this wiki page http://wiki.openvz.org/PPP_in_container)

Setting up checkpoint...
  suspend...
  dump...
CPT ERR: ffff81000dc61000,101 :unsupported chrdev 108/0
Can not dump container: Invalid argument
Error: unsupported chrdev 108/0
Checkpointing failed


Is this a bug or feature?

kernel: 2.6.18-164.15.1.el5.028stab068.9 (x86_64)
vzctl: 3.0.23

Sorry for the late answer. The problem occurs only if a DSL connetion is active inside the CT when chekpointing happen. I solve this with custom event scripts. I had write some script inside CTs (before_stop, before_checkpointing) and I call these scripts before the corresponding events happen (close the DSL or VPN connections for example). So the problem solved and not serious.
