Hi Qiaowei, It sounds a xen/dom0 kernel problem rather than a problem specifically with buildroot.
On CentOS, buildroot currently uses a fork of the Xen4CentOS bits and pieces to get Xen and a suitable kernel. We have a plan to get back to using the standard repository, but it's a bit fiddly. For now, could you please verify whether using the current Xen4CentOS instructions [1] gets you a usable dom0?
