在VMware ESX Server 4上安装Guest OS，SCSI Controller有两种Type可供选择：
LSI Logic和Buslogic。

选择LSI Logic后，还有SCSI Bus Sharing的几个policy可供选择：
None：虚拟硬盘(Virtual Disk)在虚拟机之间不被共享；
Virtual：虚拟硬盘在同一台服务器上的不同虚拟机之间被共享；
Physical：虚拟硬盘可以在任何服务器的不同虚拟机之间被共享；

选择none的话，可以直接安装guest os，没有什么特别要说的，如果选择Virtual或者Physical方式，点Power On之后会遇到这样一段错误：

要求你确认是否使用了thick option来创建虚拟磁盘。（Please verify that the virtual disk was created using the 'thick'option.)

在GUI界面上我没有找到可以将磁盘创建成thick的方式，可以登入Vmware的后台，使用如下命令：

vmkfstools -k [path]/[name].vmdk

这个过程有点长，根据你的磁盘大小和机器性能，需要5~10分钟左右的时间。结束之后就可以启动Guest OS了。

可以用man vmkfstools查看这个命令的解释：

 -k, --eagerzero
         Convert a preallocated virtual disk to eagerzeroedthick
         and maintains any existing data.
`eagerzeroedthick`
         Space required for the virtual disk is allocated at creation
         time. In contrast to zeroedthick format, the data remaining on
         the physical device is zeroed out during creation. It might take
         much longer to create disks in this format than to create other
         types of disks.


dmidecode

下边是有关这个命令的部分显示内容：

最近做windows项目，发现windows用的虽多，却很多东西不了解。学会了一个新的方法，就是在无法连接一台机器的远程桌面，但是这台机器可以ping通的时候怎样重起它：

1.在本地机器上打开cmd，输入shutdown -i回车。

这个时候会弹出一个窗口：


点add按钮输入一个IP，然后选择shutdown还是restart，然后Option里增加几项或者加comments，然后OK，就可以重起那台机器了。

在遇到本来可以远程连接但是重起后莫名连不上远程桌面的情况下，可以采用这种方法重起机器。
