I've been running something like this:

qemu-system-aarch64 -smp 1 --enable-kvm -nographic -netdev tap,id=t0,ifname=tap0,script=no,downscript=no,vhost=on -device virtio-net-device,netdev=t0,id=nic0 \
-kernel /extra/rootfs/boot/Image -drive file=/extra/rootfs.img,id=fs -device virtio-blk-device,drive=fs -m 512 -M virt -cpu host -append "console=ttyAMA0 console=ttyS0 root=/dev/vda"


On my system -smp 2 or higher hangs in the guest kernel.
