I found that thread also.
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.
