    79    * 裡面有段談到Cloud和Virtualization的關係,原文如下-> Cloud Computing isn’t virtualization or vice versa but '''Cloud Computing creates an excellent platform for virtualization'''. Amazon’s EC2 (Elastic Compute Cloud), for example, is a __Cloud Computing environment (as the name implies) built using Xen__. Alternatively, __Google bases its Cloud environment almost entirely upon physical hardware__. Providers who create Cloud-based environments for public consumption, like Amazon’s EC2, will do so using virtualization due to its '''low cost, flexibility, and high performance'''.

    89 >Xen & Lustre 的DRBL環境:
    90 >>DRBL Server -> xen[[BR]]
    91 >>DRBL Client -> xen01, xen02 (Xen,Luster enabled Kernel)
    92    1. DRBL Client在開機過程中會額外產生veth0, veth1, veth2, veth3, vif0.1, vif0.2, vif0.3裝置,似乎是Xen的問題,此外在啟動xend服務時,會出現一些在DRBL Server Xen沒有的訊息。
    93    2. DRBL Client虛擬的VM,網路無法連接到外面,可能是drbl的環境或是開機時產生的那些網路設備影響,有待進一步追蹤。
    94 >已找到問題所在,Xen 3.1版本會使用Xen自身的netloop的,當DRBL Client開機時,在udhcp啟動前會根據netloop的數量抓到多餘的veth和vif裝置,解決方法可在kernel command時加上netloop.nloopbacks=0或是將其編譯成module ('''2008-10-24''')
    95  * '''''2008-10-21:'''''
    96    1. 用DRBL去佈署cloud環境,執行drbl-srv -i 發現少了一個套件mkisofs,查了一下ubuntu hardy裝此套件整合在genisoimage裡了,若已有安裝genisoimage可忽略此訊息。http://packages.ubuntu.com/hardy/mkisofs
    97    2. 採購的硬體到了,12顆640G硬碟和16條2G記憶體,目前缺SATA排線。之後可以構思要怎樣應用這些設備了。目前計畫是xen cluster的機器記憶體會裝到4G(1G給dom0,512M給6台domU or 1G給3台domU)
    98  * '''''2008-10-20:'''''
    99    * Xen & Lustre Kernel測試已可正常啟動Xen VM和Lustre FS,之後將用DRBL去佈署環境和survey要用那一套Xen VM management tools (ex. !OpenNebula, 小瓢蟲)較合適。
    100  * '''''2008-10-15 ~ 17:'''''
    101    1. 經過多次測試新版XEN 3.3.0,並採用source安裝於debian etch、Debian sid和ubuntu 8.04,始終有API Call的問題,在XEN maillist尚未有人提供解答,在XEN官方提供的資訊[http://wiki.xensource.com/xenwiki/DistributionSupport XEN supported Distribution],XEN對於各家Distribution的支援,目前只有fedora core 3和Mandriva才能使用較新版的XEN,而Debian目前只支援到XEN 3.0.1版,ubuntu到XEN 3.1版,所以可能改用XEN 3.1 source安裝的方式於ubuntu。
    102    2. 成功從source安裝XEN 3.1.3在ubuntu 8.04 server (AMD64)上,可以正常啟動VM,VM的網路也能正常使用,接下來測試此XEN Kernel與Lustre Kernel的整合性和穩定性。

    106  * '''''2008-10-08 ~ 09:''''' [[BR]]Trace xen 的 network-bridge,使用sh -x,結果無誤,但當中並沒有產生xenbr1,產生xenbr1的指令出現在vif-bridge,但猜測只有當虛擬機器啟動時才會執行此vif-bridge,只好先去trace xend
