Size is smaller than that. After sending the e-mail I tested and if copying size was small enough it seemingly succeeded. I was planning to use strace, but the system was needed for use and I had to resort attaching direct disk on the system. This isn't optimal as it is a test system for bigger one. Another thing to try would be probably to tie the virtual bridge to physical interface on the computer. Unfortunately I can't test the problem at the moment before I find another system to replicate the setup. -vpk
