Thank you for your response. I had set the MAC addresses via:
for i in {0..6}; do ip link set eth0 vf $i mac 02:22:25:00:00:0$i; done
for i in {0..6}; do ip link set eth1 vf $i mac 02:22:25:01:00:0$i; done
then made sure they corresponded via ip link show (see output above)
Is there something else I should be doing/checking?
Thanks.
