Now this is the situation: in one direction (from B to A) there is exactly the same error as before!.. instead from A to B, the direction that before was working, now returns this error: "End of file while reading data: : Input/output error", libvirtd crashes at the destination host, and when i restart it the vm is running (so it runs both in the destination and in the source host simultaneously!)..
weird!
