We came across this article recently. Does anyone know if libvirt-lxc under CentOS 7 is impacted by this bug? It mentions that a fix for this has been ported back as far as 3.14 kernels, but CentOS 7.1 is still only at 3.10. http://linux.slashdot.org/story/16/02/22/1715202/linux-virtual-ethernet-bug-...
