kvm 1.1.1

安装

此模块与python2.7和python 3.*兼容。模块是 在pypi上，以便可以使用pip命令安装它。

例如，在virtualenv中使用kvm：

$ virtualenv env/ --prompt "(myprog)"
$ . ./env/bin/activate
(myprog) $ pip install kvm

否则，源位于github上：https://github.com/fmenabe/python-kvm

用法

您需要从unix模块导入必要的类。管理程序是 由hypervisor对象表示，并且必须包装类型为的对象 unix.Local或unix.Remote。它理论上支持任何unix系统，但是 磁盘操作需要加载nbd模块，因此最好使用 unix.linux.Linux主机。
