fdisk /dev/xvda
The number of cylinders for this disk is set to 5221.
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)

任务完成
1.添加虚拟机硬盘，首先查看所新建硬盘所在sr-uuid：
| 1 | xe sr-list |
新建VDI：
| 1 2 | xe vdi-create sr-uuid= |
新建VBD：
| 1 2 | xe vbd-create vdi-uuid= |
应用VBD：
| 1 | xe vbd-plug uuid= |
VDI与VBD的关系：http://blog.onovps.com/archives/xenserver-sr-vdi.html
2.扩充虚拟机硬盘，首先关闭要扩充硬盘的虚拟机.
| 1 | xe vm-shutdown vm= |
查看要增加容量的vdi-uuid：
| 1 | xe vm-disk-list vm= |
扩充容量：
| 1 | xe vdi-resize uuid= |
扩充完成，然后重新启动虚拟机，进入系统将硬盘扩充到虚拟机
