制作OpenStack云平台centos6.5镜像

创建虚拟镜像

# qemu-img create -f raw Cloud_Centos6.5_64bit.img 10G

[root@localhost ~]# ll /opt/CentOS-6.5-x86_64-bin_DVD.iso 
-rw-r--r-- 1 root root 4471971840 Aug 21  2016 /opt/CentOS-6.5-x86_64-bin_DVD.iso
[root@localhost ~]# 
[root@localhost ~]# cd /tmp/
[root@localhost tmp]# 
[root@localhost tmp]# qemu-img create -f raw Cloud_Centos6.5_64bit.img 10G
Formatting 'Cloud_Centos6.5_64bit.img', fmt=raw size=10737418240 
[root@localhost tmp]# 
[root@localhost tmp]# ll Cloud_Centos6.5_64bit.img 
-rw-r--r-- 1 root root 10737418240 Jan 20 02:08 Cloud_Centos6.5_64bit.img
