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。

[root@zyq images]# /home/zyq/qemu-img convert -p -O raw generic.qcow2 generic.raw(100.00/100%)
[root@zyq images]# 
[root@zyq images]# ll generic.* -h
-rw------- 1 root root  21G Apr  6 08:54 generic.qcow2
-rw-r--r-- 1 root root  20G Apr  6 17:49 generic.raw
[root@zyq images]# ll generic.*   
-rw------- 1 root root 21478375424 Apr  6 08:54 generic.qcow2
-rw-r--r-- 1 root root 21474836480 Apr  6 17:49 generic.raw

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=100000
   100000+0 records in
   100000+0 records out
   51200000 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

   [root@zyq tmp]# fdisk test.img
