Overview

This document describes how to build a visual CentOS desktop on CVM instances with CentOS 8.2 or CentOS 7.9 installed.

Notes

By default, Tencent Cloud Linux public images are not provided with a GUI component.
Improper GUI component installation may cause a CVM startup failure. We recommend you to first back up data by creating custom images or creating snapshots.
