OpenStack CentOS-6.5 Image creation

Before. Installing the Software

Yum install libvirt libguestfs-tools QEMU-KVM Qemu-imgyum groupinstall Virtualization "Virtualization Client"-yyum-y ins Tall Libvirt libguestfs-tools-y

1. Download a minimum centos6.5 ISO file

wget Http://mirrors.163.com/centos/6.5/isos/x86_64/CentOS-6.5-x86_64-minimal.iso

2. Create an empty image file

Qemu-img create-f Qcow2/tmp/centos6.5-working.qcow2 10G

3. Create a virtual machine

Qemu-img create-f qcow2/tmp/centos6.5-working.qcow2 10G virt-install--VIRT-TYPE=KVM--name=CentOS6.5--ram=1024-- Cdrom=/tmp/centos-6.5-x86_64-minimal.iso--disk=/tmp/centos6.5-working.qcow2,format=qcow2--graphics=vnc,listen= 0.0.0.0--noautoconsole--os-type=linux--os-variant=rhel6
