Hi,
I've bisected the following failure of the virtio_net linux v4.10 driver
to probe in QEMU v2.9.0-rc1 emulating a MIPS Malta machine:
virtio_net virtio0: virtio: device uses modern interface but does not have
VIRTIO_F_VERSION_1
virtio_net: probe of virtio0 failed with error -22
To QEMU commit 9a4c0e220d8a ("hw/virtio-pci: fix virtio behaviour").
It appears that adding ",disable-modern=on,disable-legacy=off" to the
virtio-net -device makes it work again.
I presume this should really just work out of the box. Any ideas why it
isn't?
Cheers
James
