刚才试了，这几个键也完全没发生作用。这台主机是一台 XEN 机器 （XEN 系统 IP 是 192.168.1.100）， 上面 192.168.1.2 是这台 XEN 里面一个虚拟机。我今天用 Putty 连接到这台 XEN 主机，并且打开 Putty 的日志功能，然后登录 root 后直接使用命令 # xm destroy RH （这里面的 RH 是 192.168.1.2 机器在 XEN 里面的 Domain Name） 使用上面这个命令把 RH 强行关机后，然后再用 # xm start RH 把 192.168.1.2 再开机来，这个时候，发现这个系统启动的时候停在了下面那句红色的行上面，我已经等了几个小时，按了全部按键，但是也是没有用，情况就跟上面进到系统 2 分钟后的情况是一样。 使用 #xentop 的结果显示 192.168.1.2 的 CPU 是 100% Linux version 2.6.18-348.AV04xen (gcc version 4.1.2 20080704 (Red Hat 4.1.2-52)) #1 SMP Fri Jan 18 17:44:38 MST 2013 BIOS-provided physical RAM map: Xen: 0000000000000000 - 0000000040000000 (usable) 296MB HIGHMEM available. 727MB LOWMEM available.

这个帖子发在C#版貌似不太合适。移到Linux版会有更多人讨论。
可以接触到主机，并且通过 SSH 访问都可以。在主机操作的时候，也是大概 2 分钟的时候就在提示符下不能动，或者正在运行的的命令也是不能动。
在 SSH 的时候也是一样。请继续帮忙。
刚才试了，这几个键也完全没发生作用。这台主机是一台 XEN 机器 （XEN 系统 IP 是 192.168.1.100）， 上面 192.168.1.2 是这台 XEN 里面一个虚拟机。我今天用 Putty 连接到这台 XEN 主机，并且打开 Putty 的日志功能，然后登录 root 后直接使用命令
# xm destroy RH （这里面的 RH 是 192.168.1.2 机器在 XEN 里面的 Domain Name）
使用上面这个命令把 RH 强行关机后，然后再用
# xm start RH
把 192.168.1.2 再开机来，这个时候，发现这个系统启动的时候停在了下面那句红色的行上面，我已经等了几个小时，按了全部按键，但是也是没有用，情况就跟上面进到系统 2 分钟后的情况是一样。

貌似是你的系统本身有问题了
刚才按住 Ctrl 键，然后，对其他键一轮狂按，居然意外发现一件意想不到的事，现在系统可以恢复写命令了，但是所有服务都停止了。我不知道是按了些什么键，但是根本 Putty 输出的日志网上一查，好像是 SysRQ网上搜索有这样一个贴子介绍： http://www.ibm.com/developerworks/cn/linux/l-cn-sysrq/index.html下面两行是发生问题时的输出：#> ls (这一行 ls 命令就是停住的地方，实际上所有命令在此处都一样会停住）
