1 在宿主机安装 virsh相关组件

yum install qemu-img
yum install -y libvirt
yum install virt-install
yum install qemu-kvm
yum install qemu-kvm-tools
yum install virt-manager

2 开启libvirt服务

systemctl start libvirtd
systemctl enable libvirtd

3 下载ARM的centos7.6镜像文件，上传到宿主机

wget https://mirrors.aliyun.com/centos-vault/altarch/7.6.1810/isos/aarch64/CentOS-7-aarch64-Minimal-1810.iso?spm=a2c6h.25603864.0.0.21708428Ojgmcf

4 离线安装qemu-system-aarch64 及相关依赖

sudo yum install zlib-devel 
sudo yum install glib2-devel 
sudo yum install pixman-devel

wget https://download.qemu.org/qemu-2.11.0.tar.xz
tar xvJf qemu-2.11.0.tar.xz
cd qemu-2.11.0
./configure --target-list=aarch64-softmmu --enable-seccomp
make
sudo make install

5 edk2 离线安装 (edk2里面有UEFI固件)

6 应对 seccomp 的错误

vi /etc/libvirt/qemu.conf 
#将seccomp_sandbox置为-1

若仍无法解决，则安装libseccomp补丁

https://cloud.tencent.com/developer/article/1162100
#中途需要一步步的根据问题进行指定组件安装和权限设置
#该连接上的libseccomp需要源码安装，解压后需要yum下载auto make组件
yum install auto make
aclocal
autoconf
autoheader
automake --add-missing
autoreconf -vif
./configure --enable-seccomp
#还需额外安装libtool  
yum install libtool

在通过./configure 生成makefile时已经make，也会有几个错误，

--1.安装gperf ： yum install gperf

--2.make前开放gperf权限

find / -name arch-gperf-generate

Chmod 777 [gperf]

./configure --enable-seccomp

7 创建磁盘文件

qemu-img create -f qcow2 /mnt/test.img 100G

8 创建xml配置文件，参考如下：
