首先调整磁盘大小为60G
点确定后,重启虚拟机OS

The number of cylinders for this disk is set to 7832.
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)

，偶尔也要现实和虚伪一点，因为不那样做的话，很难混。
