can't access internet from host

[Lane]

Hi,

I start a guest using the following line. The problem is, I can't
reach the internet from the guest, but I can ssh into the guest from
the host.

            qemu-system-x86_64 \
                -cpu host \
                -smp 2 \
                -drive format=raw,file=./my-gentoo.img,if=virtio \
                -m 2G \
                -kernel ./kernel-${KVERS} \
                -initrd ~/my-initramfs.cpio.gz \
                -append "root=/dev/vda console=ttyS0 video-nofb
resolution=1024x768" \
                -serial stdio \
                -device virtio-net,netdev=net0 \
                -netdev tap,id=net0,ifname=tap0,script=no,downscript=no \
                --enable-kvm

Here are the interfaces on my machine.

Anyone have thoughts where I'm going wrong?
