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

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？
