Having some troubles to migrate a Debian 6 container via online migration. When a user is logged in via SSH on the server, it will give the following error :

Setting CPU limit: 400
Setting CPU units: 1000
Setting CPUs: 4
Setting devices
Restore error, undump failed: Input/output error
Error: can't open file /dev/ptyp0 
Error: rst_file: -5 27003688
Error: rst_files: -5
Error: make_baby: -5
Error: rst_clone_children
Error: make_baby: -5
Error: rst_clone_children
Container restore failed

When logging all users out of SSH, it works fine. I know this was a problem some years ago with older versions of Debian. Any one knows to to fix this, so i don't have to kill any SSH connection.

Thanks in advance!

Centos 6.5
vzctl version 4.7.2
kernel 2.6.32-042stab093.4

Versions are the same on both sides.
