查看现成的磁盘文件

        磁盘文件可以通过kvm、vmware、virtualbox等软件进行创建，但是需要将vmdk，qcow2等格式的自盘文件转换为raw格式。

手动创建磁盘文件

1. 创建磁盘文件

   [root@zyq tmp]# dd if=/dev/zero of=/tmp/test.img bs=512 count=100000100000+0 records in100000+0 records out51200000 bytes (51 MB) copied, 0.0909236 s, 563 MB/s[root@zyq tmp]# ll test.img  -rw-r--r-- 1 root root 51200000 Apr  7 09:00 test.img[root@zyq tmp]# ll test.img -h-rw-r--r-- 1 root root 49M Apr  7 09:00 test.img

2. 创建分区
