虚拟主机系统

但是无论是跨所有网络虚拟主机系统上一致有效的升级，还是彼此独自运行烦琐而不完善的方案，都不足于阻止人们使用低技术含量的网页设计器。

这个工具可以与kvm模块协同工作，使用/dev/kvm来加载客户操作系统，将它与虚拟磁盘（主机操作系统中的一个普通文件）关联起来，然后启动客户操作系统。

This utility works with the kvm module , using / dev / kvm to load a guest , associate it with the virtual disk ( a regular file in the host operating system ), and then boot it .

另一方面，近年来流行的虚拟机部署在削减了物理服务器数量的同时，由于其低成本、易扩展的特性，大大增加了虚拟主机数量和系统复杂性，对监控工作提出了更高的要求。

In recent years , the virtual machine has low cost and scalable features , it reduce the number of physical servers , but increase the number of virtual hosts and system complexity , and require more monitoring work .
