This means you have given QEMU a command line which defines a
network card but no network backend, so you get a virtual bit
of ethernet that's not connected to anything. If you're using
old-style "-net nic,..." then you must also pass "-net user" or
some other -net option specifying the backend. Similarly if
you're using new-style -device to specify the network adaptor
type then you must also pass a -netdev option to specify the backend.

(If you specify no -net/netdev options at all then you get a
default which is -net user and some network adaptor which
depends on the machine type; but if you specify any -net options
then you get no defaults provided by QEMU and you have to
specify all of the relevant options yourself.)

is worth reading if you haven't already found it.
