Hello,
we have a strange problem on a fresh install of CentOS 6.5. On the server we want to use Xen to host paravirtualised guests (the system has no hardware virtualization support). To manage the domain we would like to use libvirt. Xen and libvirt are set up as described here:

When we try to create a new domain this does not work. In /var/log/xen/xend.log we have to the following error:
Could you please post the output of xm dmesg?

Are xend and libvirt running as root? Do you have SELinux enabled?
