[Qemu-discuss] Ubuntu installation shows "No network interfaces detected"

[Da Zhang]

Hi guys,

I am trying to create an Ubuntu ARM disk image for my gem5 ARM experiments.
The installation always shows "No network interfaces detected".
This is my command for running qemu:

qemu-system-aarch64 \
    -cpu host \
    -device virtio-scsi-device \
    -device scsi-cd,drive=cdrom \
    -device virtio-blk-device,drive=hd0 \
    -drive
"file=ubuntu-16.04.5-server-arm64.iso,id=cdrom,if=none,media=cdrom" \
    -drive
"if=none,format=qcow2,file=ubuntu-16.04.5-server-arm64.img,id=hd0" \
    -pflash "ubuntu-16.04.5-server-arm64-flash0.img" \
    -pflash "ubuntu-16.04.5-server-arm64-flash1.img" \
    -m 1G \
    -machine virt \
    -enable-kvm \
    -nographic \
    -net nic,netdev=n1 \
    -netdev user,id=n1 \
    ;

I ran it on a "ROCKPro64 64-bit Hexa-Core Computer" ARM borad with KVM
enabled. Any suggestions to fix "No network interfaces detected"?

best,
