Thanks a lot. 

Please don't top post. Please always keep qemu-ppc CC'ed.

I am using the newest version of QEMU, which is QEMU 1.5.0. I want to test my network card driver for NE2000. But it seems like it doesn't support NE2000 when I add attribute -M ref405ep -cpu 401100c4 or -M taihu -cpu 401100c4. Because after running the virtual machine, there warning shows up:

Warning: hub port hub0port1 has no peer
Warning: vlan 0 with no nics
Warning: netdev hub0port1 has no peer
Warning: requested NIC (anonymous, model ne2k_pci) was not created (not supported by this machine?)

I read the QEMU Emulator User Documentation, it said the user can add attribute "-net nic, model=?" to get the list of available devices for the specific target.
But it doesn't work. 

So what can I do for creating a NIC in ref405ep or taihu platform? Or if both of  these platforms can't add NIC, what else platforms which runs with CPU powerpc 405 can add a NE2000 NIC or other network card?

It looks as if the 40x machine models don't spawn NICs according to the -net configuration then. As mentioned in my earlier email, they aren't actively developed anymore. Currently actively developed targets are: e500plat, mpc8544ds, bamboo, prep, g3beige, mac99, pseries.

You can try to spawn the ne2k device manually using -netdev and -device. If the PCI adapter on the respective SoCs has been qdev'ified, that should work despite the -net hickups.
