Warnings during the virtio-net-failover test

[Thomas Huth]

 Hi Laurent,

today I noticed that there are quite a bunch of warnings during the 
virtio-net-failover test:

$ QTEST_QEMU_BINARY=./qemu-system-x86_64 tests/qtest/virtio-net-failover
/x86_64/failover-virtio-net/hotplug_1: qemu-system-x86_64: warning: Primary 
device not found
Virtio-net failover will not work. Make sure primary device has parameter 
failover_pair_id=standby0
OK
/x86_64/failover-virtio-net/hotplug_1_reverse: OK

OK
/x86_64/failover-virtio-net/multi/out: OK
/x86_64/failover-virtio-net/multi/in: OK

I assume they are false positives? If so, could you please come up with a 
patch to silence them, since they are quite confusing...?

 Thanks,
