virt-customize 主要是協助自定義 QCOW2 (QEMU Copy On Write) 映像檔的工具，由 libguestfs-tools 提供檔案。該格式經常用於 KVM、OpenStack、oVirt 等以 KVM 為基礎的虛擬化平台，該修改方式也為 Red Hat 官方所正式支援的方式，本文將提供下列常用自定義 qcow2 映像檔之指令使用方式

本文主要是以 Red Hat Ceph Storage (RHCS) 及依據兩份 Brief: How to configure Red Hat Ceph Storage 和 Reference Architecture: Red Hat Ceph Storage hardware selection guide 文件為基礎撰寫，現行Red Hat 官方發布的版本號來到 v3.2

前言

接續上篇 Build ONOS Cluster，部署運行後，總會需要打個 patch 升級一下，故本篇記錄該流程

現在製作 win7 USB 安裝碟變得十分容易, 只要下載 Windows 7 USB Download Tool 把 iso 放進去即可

但很多時候會遇到一個問題 We were unable to copy your files. Please check your USB device and the selected ISO file and try again. 此時就需要對 USB 做 Format 的動作
