####Zstack 镜像和OpenStack差异主要在agent的安装和datastore。

####CentOS 8 和CentOS 7 差异，主要在升级内核的源，安装的包。

## CentOS 7.9 虚拟机，内核版本升级到5.4，这样virt 运行速度快很多。

yum install centos-release-openstack-train -y

yum install diskimage-builder -y

yum install libguestfs-tools-c libguestfs-tools libguestfs -y

#设置完成后，不需要使用virt都需要export

vi .bash_profile

export LIBGUESTFS_BACKEND=direct
