Xenstored is only useful on a dom0 system which means that /proc/xen/capabilities should be present. Hence xenstored won't start if it isn't. The most likely explanation why this is occurring is that you didn't boot your kernel via the hypervisor. The xen-hypervisor package should give you a boot item to use if you use grub2. See https://fedoraproject.org/wiki/Features/XenPvopsDom0 for how to do this if you have problems.
Xenstored is behaving correctly for the circumstances it finds itself in.
