Debian 安装使用 Xen
Debian 安装使用 Xen安裝步骤:
1.準備 64 bit xen 的環境
apt-get install xen-linux-system-2.6.18-4-xen-686 xen-tools xen-docs-3.0 libc6-xen file xen-hypervisor-3.0.3-1-i386-pae bridge-utils
2.安装核
apt-get install xen-linux-system-2.6.18-4-xen-vserver-686
3.修改設定檔 /etc/xen/xend-config.sxp
將 (network-script network-dummy)
改為 (network-script 'network-bridge netdev=eth0')
PS: netdev=eth0 請使用實際使用的網路介面
ex: 共有四組網路介面 使用第三張網卡跟外面互連 則設定 netdev=eth2
以下類推
不过建议就改成netdev=eth0
4.進系統後確認已有 xen support
Shell> uname -a
Linux debian 2.6.18-4-xen-amd64 #1 SMP Wed Feb 21 20:46:15 UTC 2007 i686
GNU/Linux
5.
更改locales，添加en_US.ISO-8859-1同时保留原有的en_US.UTF-8，将新添加的en_US.ISO-8859-1设为 Default Locale。更改/etc/environment内容为LANG="en_US"，重新运行locale-gen。可能还有修改时区！
reboot
-----------------------------
6.更改/etc/xen-tools/xen-tools.conf
--hostname daist2 \
--fs ext3 --dir /srv \
--dhcp \
--cache no
--dist etch \（如果发现后面有时区错误，建议修改为sarge试试，我改了就好了，也不知道为什么！）
--mirror [url]http://ftp.sjtu.edu.cn/debian[/url] \
--debootstrap \
--kernel /boot/vmlinuz-2.6.18-4-xen-vserver-686 \
--initrd /boot/initrd.img-2.6.18-4-xen-vserver-686
7.后面可能会发生错误，关于语言的，建议在第八步前加入此步骤，很多网上都没讲！
不过您可以跳过试试，可能不会错，错了在回来改也没事哦！
LC_ALL=C;export LC_ALL ; LC_CTYPE=C ; export LC_CTYPE;
8.建立guest os :
xen-create-image --hostname daist2 --dir=/home/xen --ip=192.168.18.109 --gateway=192.168.18.1 --netmask=255.255.255.0 --force --image=full
后面会出现这样的文档，若一样别得意，不一定对，若不一样，呵呵，你说呢？
（可以查考/var/log/xen-tools/daist2.log，跟踪安装情况）

10.OK，很强大拉，对拉！
11.完成上面的步骤后，在/etc/xen/会自动产生与相应的配置文件，文件名称为hostname.cfg，在这个例子就是testvm01.cfg，可以根据需要自行更改此文件。
12.reboot建入新的核中吧，我进入原来的系统，以为一直错了，很痛苦！
13.啟動 guest OS
Shell> xm create daist2
4.2 觀看 已啟用的 guest OS
Shell> xm list
4.3 關閉已啟用的 guest OS
方式一：
Shell> xm shutdown etch.example.com
方式二：
Shell> xm destroy etch.example.com
一的作法如同一般關機程序下的 poweroff 命令
二的作法等於是跳電或電源供應中斷等直接拉掉電源的意思
4.4 登入 guest OS
Shell> xm console etch.example.com
4.5 跳出 guest OS
