安装KVM
- centos8源里没有qemu-kvm-tools，libvirt-python，bridge-utils软件包
- pkgs.org
## 安装工具包

- libvirt-python，libxml2-python，python-websockify在centos8源中没有提供，需单独下载安装
- pkgs.org

DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0 will drop support for Python 2.7 in January 2021. More details about Python 2 support in pip can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support pip 21.0 will remove support for this functionality.
