That page tells you how to build your kernel. You will need to enable
Xen drivers in you kernel configuration by yourself.

If you don't have Xen device drivers in Dom0 the toolstack will not
work. The error messages are clear enough.

Sorry Wei, I think I don't catch what you mean. So is my Dom0 linux kernel config wrong, so that the dom0 kernel don't have Xen device drivers? I compile the dom0 kernel with this config file: http://xenbits.xen.org/people/sstabellini/config

BTW, when I type "xl info" it works right. But when I type "xl list" or "xl create domU_config", it will halt. So can you tell me what should I do? Thanks!
