avoid detecting xen dom0 as virtual machine
The current vm detection for xen was introduced in <a class="bz_bug_link
bz_status_RESOLVED bz_closed"
title="RESOLVED FIXED - systemd-detect-virt and hostnamectl fail to detect Xen PV"
href="show_bug.cgi?id=61491">Bug 61491</a>.
This implementation lacks the distinction between Xen dom0 and Xen domU.
Both, dom0 and domU are running inside the hypervisor.
Therefore systemd-detect-virt and the ConditionVirtualization directive detect
dom0 as a virtual machine.
However, dom0 is not using virtual devices but is accessing the real hardware.
Therefore dom0 should be considered the virtualisation host and not a virtual
machine.
Problems from this arise for example when using ConditionVirtualization in a
services file for smartd. It won't check the harddisks on dom0 because of the
vm detection.
Attached patch solves this.</pre>
