As the person who both reported the bug and posted the patch that fixes 
it, I can verify that the problem is unrelated to the kernel version or 
libvirt, (or VFIO for that matter, other than the tangential fact that 
some people use VFIO to assign SRIOV VFs to guests), but is completely a 
bug in the latest release of libnl:

Update libnl and it will be solved.
