I spent also some time finding a suitable way to configure qemu (for aarch64), so came to the bridge interface option as this way I can do a diskless setup. note whoami -> is the user you intend to run the qemu and you can replace eth0 with your ether device ====================== TAP NETWORK ====================== Setup Create a bridge brctl addbr br0 Clear IP of eth0 ip addr flush dev eth0 Add eth0 to bridge brctl addif br0 eth0 Create tap interface tunctl -t tap0 -u `whoami` Add tap0 to bridge brctl addif br0 tap0 Make sure everything is up ifconfig eth0 up ifconfig tap0 up ifconfig br0 up Check if properly bridged brctl show Assign ip to br0 dhclient -v br0 Cleanup Remove tap interface tap0 from bridge br0 brctl delif br0 tap0 Delete tap0 tunctl -d tap0 Remove eth0 from bridge brctl delif br0 eth0 Bring bridge down ifconfig br0 down Remove bridge brctl delbr br0 Bring eth0 up ifconfig eth0 up Check if an IP is assigned to eth0, if not request one dhclient -v eth0 https://wiki.qemu.org/Documentation/Networking https://www.qemu.org/2018/05/31/nic-parameter/
