XRV9K > 7.4.1 : How to add qemu option on some interfaces ?

[achelminski]

Hi,

It seems that starting Cisco XRV9K version 7.4.2, ARP resolution when using virtio-net-pci is no more working unless you specify some option on the traffic interfaces (not the first 3).
Is there a way to do so ?

Thanks.
Alexandre.

Hi, Some more detail, today when xrv9k is launch, running QEMU is
qemu-system-x86_64 -nographic
-device virtio-net-pci,addr=3.0,multifunction=on,netdev=net0,mac=50:0f:00:13:00:00 -netdev tap,id=net0,ifname=vun001000f01300,script=no

It seems that it should be:
qemu-system-x86_64 -nographic
-device virtio-net-pci,addr=3.0,multifunction=on,netdev=net0,mac=50:0f:00:13:00:00 -netdev tap,id=net0,ifname=vun001000f01300,script=no

How can I add these option ?

Thanks a lot
