kickstart+virt-install安装虚拟机

本文提供的方法适用于在远程服务器的kvm+qemu环境中部署CentOS虚拟机。

#!/bin/bash
set -xe
diskimage=/var/lib/libvirt/images/centosvm.qcow2
echo "Creating qcow2 disk image.."
qemu-img create -f qcow2 -o preallocation=metadata $diskimage 40G
#fallocate -l `ls -al $diskimage | awk '{print $5}'` $diskimage
echo `ls -lash $diskimage`
