This error is caused by a version mismatch between the version of the 
hypervisor you built, which is 4.16, and the packaged version of Xen on 
Debian, which is Xen 4.14. On Debian, Xen 4.16 packages are not 
available. If you build Xen 4.14 and boot the Xen 4.14 hypervisor 
version, the Debian xen-utils and xen-utils-common packages should 
function properly.
