1， 编译支持aarch64的qemu
git clone https://github.com/qemu/qemu.git
git checkout origin/stable-3.1  -b stable-3.1
./configure --target-list=aarch64-softmmu && make -j 30
make install

2， 准备操作系统镜像（以centos做实验）和efi镜像
$wget  http://cloud.centos.org/altarch/7/images/aarch64/CentOS-7-aarch64-GenericCloud-1606.qcow2.xz
$wget http://releases.linaro.org/components/kernel/uefi-linaro/16.02/release/qemu64/QEMU_EFI.fd

3， 配置登陆的用户（假设是mockbuild用户）
$mkdir cloudinitiso
$cd cloudinitiso

$cat user-data
#cloud-config
user: mockbuild
password: atomic
chpasswd: {expire: False}
ssh_pwauth: True
sudo: ['ALL=(ALL) NOPASSWD:ALL']
groups: mock
shell: /bin/bash
$cat meta-data
instance-id: Atomic0
local-hostname: atomic-00

根据上述两个文件制作image：
$genisoimage -output atomic0cidata.iso -volid cidata -joliet -rock user-data meta-data

4,  根据操作系统镜像、efi镜像和配置信息镜像，编写启动脚本：
#!/bin/bash
qemu-system-aarch64 \
-smp 8 \
-m 10G \
-M virt \
-cpu cortex-a57 \
-bios QEMU_EFI.fd \
-nographic \
-device virtio-blk-device,drive=image \
-drive if=none,id=image,file=CentOS-7-aarch64-GenericCloud-1606.qcow2 \
-device virtio-blk-device,drive=cloud \
-drive if=none,id=cloud,file=./cloudinitiso/atomic0cidata.iso \
-netdev user,id=user0,hostfwd=tcp::10022-:22 \
-device virtio-net-device,netdev=user0

启动之后即可登陆；也可以新开一个窗口，通过ssh登陆：ssh -p  10022  mockbuild@127.0.0.1
