I plan to also try with a e1000 network interface model tomorrow and see how
that behaves....
Please do :)
I added e1000 and e1000e support to my kernel and changed the QEMU command to:
$QEMU -nographic \
-machine virt \
-smp 1 -m 8G \
-append "console=hvc0 ro root=/dev/vda nvme.admin_timeout=1" \
-kernel $KERNEL \
-drive file=${ROOTFS},format=raw,id=hd0 \
-device virtio-blk-device,drive=hd0 \
-device virtio-net-device,netdev=net0 \
-netdev user,id=net0 \
-device e1000,netdev=net1 \
-netdev user,id=net1
Why do you need two networking options?
And the kernel ooops:

Strange. Is there any reason you need to use the e1000? The VirtIO
networking device works for me.
