Too many PCI devices already configured. 这种错误，查网上没有答案。然后自己打开虚拟机的文件也就是*。vmx文件，用记事本打开，看到最后有很多添加新的scsi过程的代码：

红色部分就是出错的原因，把红色部分删除，恢复原状，可惜没有解决增加新硬盘的问题，有朋友说另建一个虚拟机建立一个新的ide硬盘，然后挂载过来，我试了，可是问题是我的原来虚拟机是从5.5版本升级过来的，6.04不让挂载，能想的都想了，能办的都办了，问题虽然没有解决，但是总结一个结论：总是需要时方恨当初的选择错误，呵呵，当初要是多设立硬盘大一些就不会出这样的问题了。我是无名小卒，希望转载的朋友注明出处。世上没有后悔药，接着再试，还是用原来的方法添加硬盘不能修改为ide就使用默认的scsi，然后在添加过程中一定要选择independent(独立)及persistant(永久性)，并在advance中修改为scsi:2:0或其他不是0:0的号，然后保存，再次重启系统成功启动了，回忆一下上面的错误原因，估计是我在试验scsi硬盘过程中导致了重复错误，现在删除了配置文件中的错误代码，问题骤解，所以能够顺利添加成功并启动顺利，系统启动后下面操作

Disk /dev/sda doesn't contain a valid partition table
[root@localhost6 ~]# fdisk /dev/sda
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.
The number of cylinders for this disk is set to 1044.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
