Because you didn't specify any emulated NIC in qemu command line.

Here's a link maybe you can refer:

https://www.suse.com/documentation/sles11/book_kvm/data/cha_qemu_running_networking.html


See the "Defining a Network Interface Card" section. The commonly
used model with U-Boot should be e1000 or rtl8139 (rtl8139 is
not converted to driver model though)
