VMware的改变预分配硬盘空间的方法

前几个月在这问过要改变预分配硬盘空间的问题（不是动态分配的），建议中有提到克隆的方法，试过可以完成。
今天看到VMware有一种方法，试验后也可以完成，假设拟定vmware虚拟的在e分区的win2003下，那么转到vmware的cmd下，运行
vmware-vdiskmanager -x 4Gb "E:\vm\win2003\Windows Server 2003 Enterprise Edition.vmdk"
C:\Program Files\VMware\VMware Workstation>vmware-vdiskmanager -x 4Gb "E:\vm\win
2003\Windows Server 2003 Enterprise Edition.vmdk"
Using log file C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\vmware-Administrator\vdiskmana
ger.log
Grow: 100% done.
The old geometry C/H/S of the disk is: 261/255/63
The new geometry C/H/S of the disk is: 522/255/63
Disk expansion completed successfully.
WARNING: If the virtual disk is partitioned, you must use a third-party
utility in the virtual machine to expand the size of the
partitions. For more information, see:

意思是给你的虚拟系统的“硬盘”增加到4G（就象你的硬盘多了n个柱面一样），注意，运行后系统还得用第三方工具把“硬盘”分区扩增了。
注意，无论你用克隆方法还是命令行方式，原来的快照都会丢失。
参考一下：
VMware Virtual Disk Manager - build 12544.
Usage: vmware-vdiskmanager.exe OPTIONS diskName | drive-letter:
Offline disk manipulation utility
Options:
-c : create disk; need to specify other create options
-d : defragment the specified virtual disk
-k : shrink the specified virtual disk
-n : rename the specified virtual disk; need to
specify destination disk-name
-p : prepare the mounted virtual disk specified by
the drive-letter for shrinking
-q : do not log messages
-r : convert the specified disk; need to specify
destination disk-type
-x : expand the disk to the specified capacity
Additional options for create and convert:
-a : adapter type (ide, buslogic or lsilogic)
-s : capacity of the virtual disk
-t : disk type id
Disk types:
0 : single growable virtual disk
1 : growable virtual disk split in 2Gb files
2 : preallocated virtual disk
3 : preallocated virtual disk split in 2Gb files
The capacity can be specified in sectors, Kb, Mb or Gb.
The acceptable ranges:
ide adapter : [100.0Mb, 950.0Gb]
scsi adapter: [100.0Mb, 950.0Gb]
ex 1: vmware-vdiskmanager.exe -c -s 850Mb -a ide -t 0 myIdeDisk.vmdk
ex 2: vmware-vdiskmanager.exe -d myDisk.vmdk
ex 3: vmware-vdiskmanager.exe -r sourceDisk.vmdk -t 0 destinationDisk.vm
dk
ex 4: vmware-vdiskmanager.exe -x 36Gb myDisk.vmdk
ex 5: vmware-vdiskmanager.exe -n sourceName.vmdk destinationName.vmdk
ex 6: vmware-vdiskmanager.exe -k myDisk.vmdk
ex 7: vmware-vdiskmanager.exe -p m:
(A virtual disk first needs to be mounted at m:
using the VMware Diskmount Utility.)
