3. OpenNEbula Usage

• 3.1 Environment Setup

  $ sudo vim /etc/profile
  export ONE_LOCATION=/home/one
  export ONE_XMLRPC=http://localhost:2633/RPC2
  export PATH=$ONE_LOCATION/bin:$PATH
  

• 3.2 OpenNEbula Startup

  $ sudo ONE_LOCATION/bin/one start
  

4. Problem

• Ubuntu 8.10 的kernel 2.6.27-9-server 目前只support DomU (no Dom0) 2008/12/10

5. 想法

• OpenNEbula的控制介面非常簡單明瞭，DRBL是否也可加入類似的介面來監控和管理node。
• 是否撰寫Web版的OpenNEbula介面，讓外界的使用者可以透過簡單的點選來創建自己的VM？
