The recent change to QemuOpts for the -net nic option breaks specifying -net nic,... more than once. The net_init_nic function's return value in net.c is a table index, which is non-zero after the first time it is called. The qemu_opts_foreach function in qemu-option.c receives the non-zero return value and stops processing further -net options (like associated -net tap options). It looks like the usb net function makes use of the index value, so the fix might best be to have qemu_opts_foreach check for a return code < 0 as being an error?
