When -net socket fails, it first reports a specific error, then a generic one, like this: $ qemu-system-x86_64 -net socket, qemu-system-x86_64: -net socket: exactly one of fd=, listen=, connect=, mcast= or udp= is required qemu-system-x86_64: -net socket: Device 'socket' could not be initialized Convert net_socket_*_init() to Error to get rid of the superfluous second error message. After the patch, the effect like this: $ qemu-system-x86_64 -net socket, qemu-system-x86_64: -net socket: exactly one of fd=, listen=, connect=, mcast= or udp= is required This also fixes a few silent failures to report an error.
