ubuntu11.10的内核不是已经支持xen了吗，为什么我安装xen之后，xend服务开启不了
并且我还尝试编译过支持xen的内核，仍然开启不了，输入 xend start就报错如下：

xc: error: Could not obtain handle on privileged command interface (2 = No
such file or directory): Internal error
Traceback (most recent call last):
File "/usr/sbin/xend", line 36, in <module>

xc = xen.lowlevel.xc.xc()
xen.lowlevel.xc.Error: (1, 'Internal error', 'xc_interface_open failed: No
such file or directory')

求指导，到底怎么回事……

你确定你进的是xen内核？

那到底怎么选择呢？重启以后按住shift在grub的list中没有xen的选项啊，求指教——到底该怎么改那个grub文件才能识别？

应该是装完xen之后，自动在grub菜单上生成一个项目，可以选择xen内核的。进这个内核，就可以启动xend服务了。

不过我选了xen内核之后，进不去桌面了
