[root@localhost ~]# rpm -qa | grep cloud-init
cloud-init-0.7.6-3.x86_64
[root@localhost ~]# rpm -qa | grep growpart
[root@localhost ~]#

Download the cloud-utils-growpart-0.27-10.x86_64.rpm package (from http://repo.huaweicloud.com/euler/2.2/os/x86_64/Packages/), upload the package to the VM, and run the following commands to install it:
