And also remove the EnvionmentFile and such. Anyhow I've taken for 
spin these patches:

 tools/hotplug: add wrapper to start xenstored
 tools/hotplug: remove EnvironmentFile from xen-qemu-dom0-disk-backend.service
 tools/hotplug: use XENCONSOLED_TRACE in xenconsoled.service
 tools/hotplug: use xencommons as EnvironmentFile in xenconsoled.service
 tools/hotplug: xendomains.service depends on network
 tools/hotplug: remove XENSTORED_ROOTDIR from xenstored.service
 tools/hotplug: remove SELinux options from var-lib-xenstored.mount

from you  https://github.com/olafhering/xen.git staging-for-4.5.0

and they fixed the issues I saw. That is I can boot Fedora Core 21 with
the sources being built out (plus said patches above)
