This works just fine for qemu-system-x86, but not for SPARC with lance NIC:

qemu-system-sparc -m 256 \
       -netdev vde,sock=/tmp/vde0,id=vde0 -device lance,netdev=vde0 \
       -netdev vde,sock=/tmp/vde1,id=vde1 -device lance,netdev=vde1 \
       -hda vm0.img

qemu-system-sparc: -device lance,netdev=vde0: Parameter 'driver' expects pluggable device type

It looks like PCI/sysbus emulation is incomplete/broken on SPARC.
Assuming that x86 is OK, what SPARC-specific stuff should I check?

Thanks,
Dmitry
