xenserver中的windows vm安装后可以通过xencenter设置从光驱启动,而linux vm则没有这样的选项,可以通过以下命令行解决:
xe vm-param-set uuid=546f896a-ebe6-8071-2c31-b9214dc1d1b5 HVM-boot-policy=BIOS\ order
xe vm-param-set uuid=546f896a-ebe6-8071-2c31-b9214dc1d1b5 HVM-boot-params:order="dc"
uuid为vm的uuid,order中的d表明光驱,c表明启动硬盘。这样设置完后通过xencenter中的虚机属性也可以设置启动顺序了。

如果你确定一定要禁止该服务,请打开安全卫士--实时保护--高级设置--保护360安全卫士--关闭自我保护后,还有核心保护也要关闭,然后进入进程服务管理(随便你怎么进!)禁止启用即可。
我觉得要是你真不喜欢多的这些进程,你最起码也要在控制面板里把该进程设置为手动,因为这几个进程真的很重要!

今天想去下载王小峰博客上的音乐,像往常一样,把http://www.wangxiaofeng.net/mp3player.xml拉回来,发现格式都乱了,像以上,只有2行(<player ×××>到</player>为一行)。
想过将http与mp3之间的内容提取出来,但不知道如何入手,最后想出先将它分行,再提出mp3地址
sed "s/<song/\n\r<song/g" mp3player.xml |cut -d\" -f2
输出,有首歌的歌名不是英文,乱码了,Mark_Mulcahy-Be_Sure.mp3

注意,如果是vi mp3player.xml,替换时,换行符则只有\r,而用sed时则是\n\r
:s/<song/\r<song/g
Windows下用Notepad++打开正则表达式进行替换,换行符是\n
单命令用
grep -oP '(?<=song path=")[^"]*(?=" title=)' mp3player.xml
更简单的
grep -o 'http[^"]*\.mp3' mp3player.xml

1.使用XenCenter工具,连接至Server,Tool-->License Manager-->选择要更新License的服务器,点击Activate....按钮.如果,此服务器可以直接连接到外网,将可以直接获取LIC文件安装,如果不能连接至外网,将会出现更新失败提示,并提示保存申请License文件.选择将申请文件保存.
2.访问:https://activate.vmd.citrix.com, upload申请文件.
3.填写相关信息,主要是MAIL地址,用来接收License 文件.提交.
4.打开邮箱下载License文件.
5.使用Winscp工具将License文件复制到XenServer的/etc/xensource/下,并重新命名为license.
6.重新启动XenServer.
7.License更新完成,可以正常使用.
关于Citrix公司的XenServer免费使用,个人理解,虽然为免费版本,但为了方便管理, 以及获取用户的相关信息,Citrix采用了Free License管理的模式,在到期后,用户只需要再次重复申请新的License文件并进行License安装即可.不会影响XenServer的正常使 用.但是,Citrix公司并未发表声明永久性提供免费使用,至少我没有找到.特别在正式的生产环境,还是建议大家购买正式的服务,以提供更高的性能以及安全的合法的保障.
