VM与VPC共存(续)
小编觉得挺不错的,现在分享给大家,帮大家做个参考.
VM和VPC是大家熟知的虚拟机软件了。有人喜欢VM,有人喜欢VPC,萝卜白菜,各有所爱。 VM优点:支持USB设备;虚拟网卡众多,可以模拟多子网环境;显卡驱动要比VPC好,VPC只支持1280*800分辨率以下,我的1366*768无法全屏;VM自带录像功能,可以做视频教学;VM自带snapshot功能,误操作时还可以回滚。 VM缺点:跑Windows系统确实不如VPC占资源小,速度快。 VPC优点:跑Windows系统确占资源小,速度快,这恐怕是唯一的亮点了。 VPC缺点:显卡驱动在1366*768的分辨率下无法完整的全屏,尤其是对linux的图形化支持更是花屏严重;网卡仅仅包含宿主机的物理网卡和虚拟网卡,有时候做多子网环境还得利用loopback网卡,蓝牙网络,无线网卡等。 所以我一般都是VM和VPC结合使用,做cluster实验时偶尔还用到VS2005。在较早的机器上做实验时,因为机器硬件不支持虚拟化,所以不存在VM和VPC冲突的问题,当我新买了一台I5的本本后,发现VM总是和VPC冲突,并且如果同时打开多个VPC机器,还可能导致物理机蓝屏。 <?xml version="1.0" encoding="UTF-16"?> <!-- Microsoft Virtual

在网上搜索过相关的问题,大部分的矛头都指向VPC中的一个选项:
但是我将虚拟化功能Disable之后打开VPC还是会让正在运行的VM出现中断。
后来,无意中用UltraEdit(记事本也可)打开vmc文件时,仔细看了下里面的代码,代码并不复杂。
171. <enable_hw_assist type="boolean">true</enable_hw_assist>
大家看上面170-172行代码,原来这台虚拟机一启动就默认打开虚拟化开关,即使关闭了控制台的虚拟化开关也是没用的。将此项设置为false后,VPC再也没有和VM冲突了。 <enable_hw_assist type="boolean">false</enable_hw_assist> 根本原因是宿主机(物理机)不像WIN2008安装有hypervisor去调控虚拟化的硬件资源,所以如果虚拟机打开虚拟化开关会造成硬件资源争夺的情况,严重时造成物理机蓝屏。至此VM与VPC冲突问题从根本上得到解决。
