Comment 124 for bug 997978

My web search reveals this problem has been around for years and most posts conclude that the problem continues. After solving my tap0 TX packets dropped problem, I find that my VM network has random freezes a few times each day. Many bloggers on this subject say this VM network freeze is difficult to reproduce. Not for me! I can cause a network freeze on my VM in a heartbeat. Like many others, all I need to do is start a data transfer over the bridge (FTP 2Kb file or larger). When the freeze happens, ifconfig tap0 says overruns:1. This is QEMU version 1.6.2 without KVM on CentOS 6.5 version 2.6.32-431.
