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!
