That message is from /usr/lib/xen-common/bin/xen-dir. xl is not actually xl, but it's the wrapper script which tries to run xl for the current running hypervisor version.

And indeed, doing things based on running hypervisor does not make sense here. What if you try running /usr/lib/xen-4.8/bin/xl directly instead, for fun? Hans
