I just updated https://bugs.launchpad.net/qemu/+bug/1753309 with my
observations. As it turns out, the Ethernet interface on older kernels
(4.9 and older) only works with the current version of qemu. It is
possible to fix the problem by applying upstream commit 4c8777892e80b
to v4.9 and older kernels. However, I don't know if the problem is also
seen with real hardware, or if there is some other problem lurking
somewhere in qemu.
