Xen VNC
- 基本步驟請參考使用 DRBL 部署 Xen 虛擬叢集
- [備忘] 從 xm console 跳離的快速鍵為 CTRL + ]
- [狀況] 發現一個小小的問題,xen-tools 其實是採用 dom0 的 kernel 跟 initrd.img,所以 debootstrap 也是拷貝 dom0 的 /lib/modules/。加上如果我們要求 xen-tools 把 domU 的 image 檔案系統改為 reiserfs,而 dom0 自己是使用 ext3,會因為 dom0 initrd.img 沒有加入 reiserfs 的支援而致使 domU 開機時無法掛載 root filesystem。
- 在 Lenny x86_64 上的安裝步驟
