docker – can’t initialize iptables table `nat’ under qemu

Facing issue while starting docker inside s390x container under qemu on Ubuntu 18.04 host running on amd64.

Steps followed (On amd64 host):

docker run --rm --privileged multiarch/qemu-user-static --reset -p yes
docker run --privileged -it s390x/ubuntu:18.04
apt-get update
curl -fsSL https://download.docker.com/linux/ubuntu/gpg
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | apt-key add -
add-apt-repository "deb (arch=s390x) https://download.docker.com/linux/ubuntu bionic stable"
apt-cache policy docker-ce
service  docker start

Docker service not starting. /var/log/docker.log shows

Perhaps iptables or your kernel needs to be upgraded

.

Any settings needs to be changed /steps needs to add?
