Thanks. I can confirm that it works with iproute2 3.15 and breaks with
3.16 so I'm reassigning to ipoute2. 

Dear iproute2 maintainers,

Libvirt breaks with iproute2 3.16 like

Aug 11 17:44:43 bogon libvirtd: 6966: debug : virCommandRunAsync:2299 : About to run ip link add vnet18 type veth peer name vnet19
Aug 11 17:44:43 bogon libvirtd: 6966: debug : virCommandRunAsync:2302 : Command result 0, with PID 7089
Aug 11 17:44:43 bogon libvirtd: 6966: debug : virCommandRun:2150 : Result invalid value 255, stdout: '' stderr: 'Error: argument "vnet18" is wrong
: Unknown device#012'

while it works with 3.15. This was caused by upstream commit

  9a02651a87d0fd56e2e7eedd63921a050a42b3ec

Removing the check makes things work again (see attached patch).
Cheers,
