Re: [Qemu-devel] [PATCH] Adds virtio_net as the default netcard for mips boston board.

[Tommy Jin]

Hi Peter,


That command line option doesn't work for boston, although I didn't get any 
obvious error, no Ethernet card appears either.

Where can I get that arm image/command which can work well for you with " 
-netdev user,id=mynet -device virtio-net-pci,netdev=mynet" ?


Anyway, if that command line option works for arm, I'm going to investigate the 
reason.


Best regards,

Tommy

If the boston board has PCI support and it is implemented correctly
then you should be able to create a virtio network setup with
command line options like
 -netdev user,id=mynet -device virtio-net-pci,netdev=mynet

(or any other netdev backend, eg tun/tap).

I don't have a boston image/command line to test that with,
but it works for arm boards and should be the same for any
pci capable board model.
